System Design Interview Prep | Twitter

[@LailaNassali]

Thank you so much for this video! I had a system design interview for a junior software engineer role and this really helped me! I got the job :D

[@putinkhuilo4315]

Congrats!

[@0xfps]

Congratulations 🎉🎉!

[@Alyw14]

This is the most straight-forward & helpful video I've found on architecture & design interviewing. Please do more systems design interview prep.

[@spago555]

I am a non-tech PM and this video was the best most easy to follow video out there on system design. Thank you!

[@belindamarionk]

First system design video that hasn't given me headache✔️ highly recommend 💯

[@kevintiba7195]

This is a formidable presentation to understand the key takeways from a system design interview. From the notes I took, this can be apply to any type of problems (with caveats), but is definitely a great starting point

[@zipbullbear7693]

Best presentation, short, sweet and to the point...great job!

[@ahmetbcakici]

It is really so clear to understand especially for beginners, thanks!

[@sayak]

seems you have read "grokking the system design interview". this was a good revision.

[@tobiwobikun]

Really straightforward but valuable content, great job!

[@RanjuRao]

Thanks for contributing the knowledge :) Teaching is an art and this video is an example of that :)

[@rakshith3547]

So true

[@paulolopes961]

Really clear and useful, brilliant!

[@sergebyusajabo2138]

This is so useful, it helped me to learn a lot. Thank you

[@acla3232]

5:27 kinda confuse is it supposed to be kilobyte not byte? I mean 1 mb is 1 million bytes

[@geoffl]

I loved the blackboard format

[@josephwong2832]

Love your videos bro! more short system design videos would be great

[@KeepOnCoding]

Thanks Joseph! I'll try to make more!

[@jaimel6762]

Great example, thanks!👊

[@asankasiriwardena3383]

Could someone please explain why micro services architecture is not suitable here? Or is it an overkill due to the functional simplicity of the system, since we have to worry about the load of requests and amount of data?

[@thazapo]

thank you for your good explanation.

[@aditya4974]

Thanks. Looking forward to more System Design videos!

[@9893011111]

superb video man! looking for some system design tutorial / video which can teach with generalize way and implement same theories in most of the products.. & here it is .. thank you so much man, appreciate it :)

[@cloud15487]

LRU does not mean you kick out the oldest, it means you kick out whatever was not used recently (Least Recently Used). Only because 1 has an old timestamp, doesn't mean we kick it out, if we used it recently. That was kinda misleading, also I missed consistent hashing. A good video to get your feet wet though!

[@talebsouli4767]

Thank you very much brother!

[@KeepOnCoding]

Thanks for watching brother!

[@ArtyomPalvelev]

But would it use SQL or NoSQL? :) And why?

[@maratmkhitaryan9723]

[@maanickp]

Why do we use MySQL to store tweets instead of a NoSQL database like Cassandra? NoSQL databases offer better scalability, and we have to store millions of tweets every day.

[@ajisaputrars]

Just curious, is there any database and/or API section in the interview if you are applying for front-end web/mobile position?

[@henryquillin3733]

curious about this too

[@putinkhuilo4315]

Out of all the systems design videos and sites I am on, you make much more sense than others. Seriously. Your approach with the blackboard and writing what you say is the best format to learn faster. I am a big fan! My Amazon SA interview is in two days. Thank you for this!

[@SHADOW5487]

Hello bro, just found your great channel:!) Pls, keep it up u'r helping a lot of people.

[@KeepOnCoding]

Thanks for the support brother!

[@MohammedBakheet]

Thank you so much for this very informative and useful video 😇

[@jeffpeng1118]

I wonder what would happen if the interviewer asks me to design Twitter and I be like I don't know how twitter works because I don't use it

[@icarodlima]

Awesome! Thank you!

[@drewstan]

Super helpful, thank you.

[@jonasliao3780]

This is too high level for senior level interviews... useful for interns or juniors I feel.

[@bostonlights2749]

How are you generating the timeline service?

[@TheMinino123]

Thank you so much, man. This is really helpful! =)

[@adipratapsinghaps]

Can use zookeeper to get list of servers for A-M and N-Z

[@henryquillin3733]

8:40 you forgot to add the tweet content to the tweet table

[@japanboy31415]

i really hope my interview works out. I cant stand where im at right now.

[@rakshith3547]

you did not talk about newsfeed section which is a critical part of twitter SD

[@kabooby0]

Are there good books for system design?

[@ajayKumar-nl7pn]

Great explanation! Can you make a video for the same on how to pick technology stack based on your system design?

[@KeepOnCoding]

That could be an interesting video!

[@ritikapandey3473]

Can you share your views on coding this ...I mean implementation

[@sunilagarwal2007]

This is really awesome system design explanation. I enjoyed going through it and learned a lot. Thanks for making video.

[@ivantrofymenko1308]

What's the point of doing bandwidth calculation? It seems like pointless arithmetic. It doesnt drive any decisions in the rest of the design.

[@alperenozil]

You can add a CDN by referring to the calculation.

[@Dan-tg3gs]

Why is it 2 bytes per character? Shouldn’t it be 1 byte?

[@collegetv7986]

I was thinking the same

[@alexandrecourouble6483]

Unicode is 2 bytes per character. Ascii is 1 byte

[@therailgun8880]

the calculations are the hardest part for me :(

[@gerardohuidobro5811]

What college class teaches this?

[@songyincheng8888]

This video really helps a lot of people who are trying to improve the system design skills, thank you! One quick question, what software are you using for the drawing in the video?

[@ΙωάννηςΠαλιάκης]

Hahaha dude come on , you just copied the whole content from educative ?

[@sayak]

yeah. that's what has happened here.

[@l3aIIin23]

when your doing the calculation for storage and network, can you do it with a calculator? or do they expect you to do this stuff in your head
