hello everyone hi we're here with my son Seto and a lot of you on my channel asked for an example interview question or similar to do the interviews at large company too so we are here to do an example question for you which is going to say the full time of a a whole regular interview question and I prepared an interview problem for our petrol if he doesn't know what the problem yet so you will see those the thought process that goes into actually problem solving and we are going to read it to you right okay so if I go can I write you a few things about yourself before you sir okay sure so I'm currently working Fred and I oh I'm toddler and I'm when I'm mostly doing software engineering and you know guy don't solve the technical architecture of the product yeah sorry secretion yeah okay well let me let's go get right into the questions in the shirt okay we have a wonderful feeling wonderful I asked you have marker oh sure yeah okay so are you familiar with Google Docs yeah documents okay so you've noticed that people don't that you have a waist coverage between language users so the question today is how to use language to describe it in or maybe discusses architecture okay so we're trying to make a collaborative doctrine it is about that feature will look not as pricey so it just might work okay okay so so there's there various parts of a system that we can consider it essentially so it will business need to be some sort of messaging between between the client so I would people connecting with the browser and you know changes from one find me to be propagate to another so there it needs to be promo something with what targets is the thing that posting online right right now okay the Department of course how we will represent the document and rooks and changes such on mallocing and again will conserve within a solution and and then improve improve that yeah definitely needs a thing like would be a good property for the system to have and thinking things like resiliency to if you really applying it emits an update may be self-correcting yes a we okay so well thank you mister the probably really easy is me say that we have documents and users whether we don't even care about the cooperating ability to get there are just really really to store to those men and have a full users evil practices that's the nice and I got first okay so to a pretty simple system like that we can probably make the assumption that a single user will be able in at any given time yeah so for that is pretty simple to make sure I was making a daily that have my users and then a cable with with the documents which can be a simple text field and so every time a user wants to edit the document they can they can say I'll start aging then Google store databases PC user have more or less like a medics so you get inconclusive lock and you can after that when people turn the editing in your browser and in a can post request or there are modifying the document database and everybody else can can read that document access to but they cannot long time and then when you're done you say announce you release a lot and that another user can can get be okay that's all good let's go ahead and find the daily friend see how this week mandates 11 beginning complicated so I can start making me there is not so yeah I'll create complete our table Chris new beginning and I'll sure I'll live with Co the total of each table today what they will have a simple system like a username and a password and curly money I'll pay from it and there's a third column and then ultimate table which will happy their data and if only one person had love and keep on this for years oh look either I'll tell you how to use em and then we probably store which user has access to it with substitute user table right and user ID okay so the way the way this works with this database is that normally for every gene document must be very easily cool and let me know but ahead upon it and if you try a the Dolphins any game odd these are marquees so usually not original so when you use it correctly as an element we will only be back we will only say we're something every price if we either any pricing with Oakland and we able to see I can control to you and we will only allow you this modified Lippmann if their user ID is either and you can only get it out if some other user has a lump okay that's not good okay so let's stuff yeah the silver ball up the protocol and calm the user the users try and communicate with the server exactly in this people to keep up making able to have some sort of live updates at least one person's editing and the other should be see how the document is evolving in Vietnam little problem is many times okay so the simplest approach would be to actually expand this pool pump is open every time I change something back plus database and here's a lot of fine one too and let's say this piece right here is low so the way to work it Yi or what am i lookin hundred Roger and we can be coming the results agree and when we have something we can have some sort of be calm so you go and you're typing out after you have them type anything for five cycles or something that which sent a copy back to the server here there is a WebSocket connection so when you when are you arts open away web check extinction you can be paying your you create for the temptations there is a change now you've got to disclose in companies up now this is figuring us something more and for August you eat to do this sort of thing so this is actually to do this face to purchase so you can either would preferably happen if this approach and change but I will change it okay so we hope we go into that before we make hits movies multiplayer exist before the others visit in protein do let's debate cage hanging let's quickly folk all those securities verbal so I hope if there is a concerted network attacker at this point they shall keep read what kind of document you're writing and what kinds of community so what what does the record games use to sexy so I don't think it's a multi life connection so as long as these connections are over a gbgs to a domain that has about eight times of violence EA that should be enough and control offensively some other injury other places yes or any public you can and procurement yeah this is great let's look at it in through the situation based potion and then this will be both user is zoology approach that okay so to make the deep based approach and for that is like offices you have to be within into TP to dock to network often to show your business of the connection result for five minutes and during this item entity makes change our life this time to get this when they get back in line and what I'm thinking in a in a similar one or acute I'd like to be able to identify the space of a document about so negatory not just here so this single mutable copy and therefore you know this guy will say give me even the latest nachos because it's not should I have whatever can use is to put in Carter's coupler this antenna box a file command attacking pilot now we're totally even in in this very simple system if we have this you native a to be instilled happy easy chair all showing he doesn't history squeezers even if we don't use a multi-user featural or the disk feature right so where 0 yes so I mean if we easily add this your talk a lot or the television yes even if we don't take advantage of it what it is wonderful teaser editing we can still have a feature of Google Docs where you can go back on say you know don't you mix two days ago so maybe we'll fill that first and then you step to make it sure okay so okay so notionally or there is a single document entity and then a spokesman and we have a list of obedience and mother is like so when chromeless do is instead of having the date year let's say revision and then create a revision table that has data now and also had Beltran be and another right so that's curry worked so basic what happens here is for for every dollar we had a lot of revisions and every reason to link back to the devil so even in revision we have the judgment a for we don't hear the need to store a link please honor to keep your engines we know that quarry for processors we limited region by up 92 just order the light intensity their sequence and I saw the latest repeating here so that will be playing you want them yeah what do you think is shorter revisions them oh we don't really need even to take its latest ID so thank you very little that who did what one thinking it well I get I would search for performance reasons that I'm not sure being a collector getting late yeah so before me we want to talk about performance a little bit here on on the database schema how would you ensure that this is performance will are shaded so the first the first thing that comes along it's looking at lease or tutoring as a sort of build up filtering with and creating industries for the kingdom I think I'm using them predicates law yeah okay that's in this case for example here might not I'll be very often featuring getting repeated space I look now here in English Alma doesn't ID okay and you mention that sometimes we're going to eat essentially its revision so what innovative internet latest revision pretty well here if I had an index based on documents i'ii come up ID i can easily get real a trachea the Gili they will be cooking laundry okay so let's go ahead and do this smartly smell okay so okay so now every client have a look only current date to these guys so the thing that I had a great party and currently modify them so eventually they will create wearing the trick which doesn't include camp and then every client had some other versions of these litigator time where is it - okay come on you're allowing multiple people today right that's a thesis when I think creates operations had trees buckle yet they have a chain deity again so we hear their connections all okay okay so you still have one user that at 86 work okay so these guy had luck and he keeps basin region 5 which is one day when they started is really was latest version so hop on you have a great version six over the right document six here and so then this guy will say give me give me a reason six about ultimate and I have reached too low so hollow look on to know which is the latest version right so we still have a system where every time you write we occasionally what Chuck it's okay but instead of these client responding to each education by texting Ronnie copy they say they'd be shocked how you do in the meeting the API level can be depressing because these are requests later region and then do a second request I can predict or I get to say even the latest based on that and have a server lineup which is late okay so basically that every will reply say here see a sig and that request will pack what the difference would be this base approach working leather over it and then I can't line and stable chain uses here okay um yeah that's done those very good um so one wishes how does that user become places disappear okay so when the reflected the server and a cigarette to turn it grab the data for revision six - and then we can replicate this algorithm so there's when we need you to be that awkward Atlanta cz okay the whole Tisa number it should look like implementing this okay so I mean he comes with a library but I'm pretty sure for you know I wouldn't do this for libraries which is texted okay please also used to get yes so everywhere you can get depending on the language runtime so you know if it every day and I see none of my life it might be tricky to get a tech native binding experiences yes and link with the sea liner if you're eating super classes to be creating to do that okay so you have to kind of pile on this type of the document yeah sounds about right it's good I need to ease libraries of course and then the other question is how the client into this and previous versions come with a result right there you know maybe not the dish and rape robbery but this is a publication operational time so you definitely need a freaking foundation what is wrong with you use okay so I take out a configuration if the debugger it is not exist and tell us with your computations if there are ways of competing that come find us there pretty hands and you can provide to other processes I wanted to do that for productions around right create anything great solo yes between us but still have only one user face to me okay the good-looking okay state senator from practicing how kind people look for impulsive people are and so the first thing I think about is we defining these algorithms all the time and everybody sending dicks on the server and it's trivial case we don't have conflict every time you know everybody gets the update pile or less insane fate however we have problems where I'm a model here and another guy heavy laden and also the distance to that now mobile people obviating saying that line but you will be working on the same document so let's do that back in first alright okay so he said we all of your has a ball here so everybody can be I see documents and so actually explore a block so let's take every client hazard rating those competitive region documents they make some changes and not that they make it and they tended to serve so it comes right up fine now every time they write this the server will get this there will apply to this to the latest revision create a new revision here and reply with it got it okay and six now there is a problem here so they see that then you know all the other countries make in to receive the update which is there on the same line and we'll get updates these problem is will happen this so focus our thoughts and we find the both make this year so actually walking will by part to the server and eventually the third will have two new efficient sticks and stuff so the response to its time testitude not only say okay go for six but also in other changes is happened while you were right okay so how much gets old responds well it's when you well with each other in order to push and you brazen yeah that relationship when you have to write pushing you're committed to the octave Russians equally if you don't have if you your database on language that you're cooperating so then you pull the newsmen latest version actually one companies and then we try they can do the same yes yeah so basically yes and you say is a inspiration five if one do that these document alidium gracious patience April city has not been copied so it will say vertical love you want reapply the business wishing that everybody has people live here there's a conflict and anyone we try right so you can get okay so this little bit tricky I think so this goes between let me get quick and describe a little bit what in when we can't matter how much a planet is because if I made some changes in considered high and I created a new version our origins Edition server then the service is really sick then that is is that salad or music or not we're going to change this song 1210 going whenever you have it additionally and making risky Walter in the comics so there's mine chains of their stomachs so before and after your king so Allah has it come to us the fun and II cannot accomplish and consume this piece equal to five Olivia T change you know all of my change deeper protein online and he went through all the fun okay so look at me how long we have this will be user assistance and then one question is what happens if I mean online how would you how to be sorry the Christian if you mean apply and do your much changes proton times up yet you want added up with a lot please see our plan is mating local to page edit and landing the next back and then the problem is is if the context like this during your quiet it will not work so well deal with that but we can assume that a lot of people will be editing the same lines as you are doing Jimmi Klim know normally but you still intend to report like this so I mean they persistently doesn't have if the Brahmin doesn't have to be kind of server to participation another editing so you can kind of local attach like we can use other storage for that and keeping the local data and if these really some kind of a teacher if you will get an extra connection and when you have a connection can change your look State win server so yeah basically filter coffee luckily had a background Gerald try always trying to sink level six or rustic look at the other related line and it will only work similarly on a little version I get really well okay so this is pretty good if you use a chronic basis then the colloquy change but the life the lender is you may not change under our assumption so the following assumptions that people are changing okay it's wrong around their life they're not changing myself but each time they're doing a changing maybe something small so in my tea medium line calls a little bit and mind a lot a little bit but not all lies at a time so it evils of their vision you see the beauty of right now but the problem is with this system case let's say I'm on 35 and then I'm online for a while I change one people line and then eventually I don't want mine and I see where our vision what they you know 80 then this I have from version 5 with this context will roll over class but there's enough information from our gracious 5 up to 82 building unit that can apply and route 80 so how we do that so it is the assumption of the mind set on revision on the PI data segment so I'm working at a new line it is fine because of the design will take same for until the reason ATL different context change yes I mean there may be you live at it slightly moved put this video line still yours so you have a proline lock okay so if it's the same line you can probably inside line and if they agree surrounding line have T change probably to some sort of not exact month to see how how different they are and if they're more in listen stressful because you're going completely different ahead fail otherwise is there there's no very different achievements become on the other thing and thinking about hey do you need particular - DSS rebate - basically yeah announcer keep you very healthy drawl I think it would raise entertain shoes so usually how is it you have your elastic low and I mean those little holes is harder below so that's millinery hilarious email just inside content but right what happens where comment on it okay here once agree on a for my face right so there's a this is revision five and then this whole revision of the seventeen it's been one life fashionable here so there's not cheap and there's darkness and then this one has changed and is often completed on aaaa and then you have your cologne there and in here isn't changed as well so your difficult apply that but it's changeable final 70 - slowly so remember a really safe you say oh you know that has a net and then in version 7 starts having added 19 to Richmond they hate the one Israel over one changes in hey and then the next revision to is three chain two two double a and as it's also change located entry so we have all the content information to be billeted but if you just join applies to written in the you will not work right so you won't say anything about it you see as a in exterior time and then there's one last feature that could say he'll the way up to and then you have your oldest to go to subscribe here an admission how you take a move here because if you want yeah something that maybe because yet all these B's hear me this is great facial and certify me help out another color to get be from here fight under to climb and life instead of time and so on so forth and hopefully ages and we're not depending on prime would be a combination of opposition okay so this will be done of the climate that's why we concerts after you sir keep because technologies with people so you can you know I have this kind of big animators fine December can be all the same and if everything works for Calais you'll say Pacific and this not English okay so the server will stay at a certain route applied you have this bit iconic item 7b so do like gradual obligations to get you your in your hips and then in based on this latest event nullified conversions energy that you want and then the client announced as one who have no hotter ear basically crap all these catering at the ear you will have a very much stuff that have only your business every a logistic so this is everybody I tell I'm going to put on your socks equal position but but if I look at this revision economist initiated for this plan then my changes leave show me where these notes yeah service link because we were always a little nuances roaming a different thing but the changes that really showed one to tell ya so it can be other information time for the chain shows you know how to do for apply these are different things to get Celtic resonant item you have a weakness our Thursday's are not walking through better change that so the others we could do but actually when you reach this point you will act potentially have something like this document with the change here so here you can actually basically do here yes and that if I may have broken up and we won't have came out for the trees one right so differently temporary Texas population on the hottest a construction site okay no okay yes this is one common question this is this system right here was made by lying little seven ultimate refine no it work this is fixed fine as this monitoring part that I made this from five to title here stead of trying get for you sighs fine it requires you to stick a little server on the subtleness I okay yeah please still means we like to move it between document results change yes okay yeah good and then I guess this whole most of proposed them and we're extremely well my question is my question that is will not do the will I ever see any concepts no basis at well while you not see any hockey I'm pretty sure you will see your changes disappear yeah so what I think is that they had aa resolution company and they choose the version based on them completely those days very few people attend st. worth one week yes so don't they all have they don't require users monthly we don't and they gave us appropriate right yeah that makes it ok racism one more question I have is this was very similar to getting me anyway keeping because we used to get back in I understand likely unless I let him be my my main thing I'm thinking about it it gives a conference invasion system so it will include a great load of clouds and we wouldn't be able to reduce you know scale of this game we get with beta brake systems or applications new hands gratis we have to let me recall you know you spending all of these talks and our other various consultants up I'm not sure if key has been built with durability much of what they couldn't each Saturday I this is reason how much am I kept assuring the actually writing to see Vikings or position for example educators so there will be and other things to consider it found out one last time before use that and the other problem is that this is problem of nihilism yes so if you have other research databases link to those resources it would be pretty hardly surprising to do yes yes no I think okay well that was pretty great solution things wait life okay can I have your arm yeah I think it was not very long yeah all right so I think God but there's moments nailed it and I'll have all when the description of the video I'll have some first critique that a kid comes out here that state what they treated well on one thing to use as well well I think this would be a great answer this question so and I think this is generally a good question for assisting the software deniability quite often that large company at the design Commission so responsible because they really system Pro we didn't address the multiple router and latane line so I mean and on an interview that it's probably you know has to do read specifically at some point about these data structures that allow you to have multiple drivers and high dimensional consistent data stores and their structure that allow you to make leisurely operations on documents so I think Google's is not a system a simplistic system like gates and it has a more complicated algorithm so buddy I generally the visitors and problem and customs differencing a little berries all right well please run you know we want
