I am a Senior DS in a Recommeder System role and have interviewed over 200 people for a large company. I have also failed in countless interviews myself before my current role. this is a very unsatisfactory and abstract answer with zero technical depth: do not answer like this . Go into more architectural and technical depth instead of waffling . That “solution” about scaling was complete garbage in particular

[@iqjayfeng]

Hey Sachin! Would you like to come on the TH-cam channel? We would love to have you

[@sachinpaul2111]

@@iqjayfeng I would definitely . Is there a way for us to DM to discuss the details?

Is Sachin's video published yet?

@@hasnainmamdani4534 hello Hasnain, thanks for asking. I was busy with interviewing and finally ended up switching jobs. I have reached out to Jay and hopefully we can collaborate and publish this video. I am looking forward to sharing my experiences from the latest interviews as well

[@TheBjjninja]

No mention of infrastructure, SLA response time, business success metric, A/B testing, staggered rollout guardrails, etc. He just memorized some things on how collaborative filtering, kmeans, euclidean distance work which is a sign of a lower level answer.

[@kein406]

SNH for sure.

[@toomuchpoop450]

no whiteboard or screenshare thats kinda odd for SD mock

[@larigiba]

Your videos really are a blessing! There aren't many ressources out there that share interview details specifically for ML systems and this really helps out; thanks! :)

[@nikhilsahay895]

How does this qualify as mock interview !! no structure, too much talking, sounded more like Ted Talk

[@bibiworm]

I honestly can’t believe how misleading this is. This is nowhere near a true machine learning system design interview.

[@TacoMaster07]

How so?

[@illan731]

Could you give questions/answers examples from a real interview?

[@iqjayfeng]

Thanks for watching! If you want to prepare for your upcoming machine learning interview, then Interview Query has you covered! We have diverse questions to prepare for the interview and stay ahead of the curve.www.interviewquery.com/blog-machine-learning-interview-questions/

What a load of bollocks. That guy is clearly high and knows nothing about ML.

[@thedanglingpointer8411]

Hey! Great video. Can you do a ML sys design where one draws while talking.

[@samhaaf]

Any idea what technique he was suggesting to map the user features and video features onto a shared, lower-dimensional space?

[@bibiworm]

one way to do that is through two tower architecture.

It hypnotises me lol

very interesting video!

[@spire52]

Ty bro 🥺

[@sakshamjindal6992]

Don't call such interviewers who are just here to say things casually. I understand, nobody's paying him but atleast have a whiteboard. Explain things properly.

[@joyceawesome1705]

Great video for machine learning systems design. Can you make a video for Machine Learning Operations Engineering (MLOps) Sytems Design interview?

[@NukulSharma]

No where near to actual recommender system platform, it’s too bookish and focusing only around basic algo,
- no view on architecture was presented
- not highlighted scaling algo and platform
- not discussed problems like cold start, ever growing features, ab test, metrics etc

really really bad, 0 help

Hi there please help me I am too confused about what to learn to get a job as a data analyst I have around 3 month time I am a fresher in INDIA will I be able to land a job as a data analyst.

You can do it. This video is beyond what you will have to answer during a data analyst interview. Keep studying and reaching out to people for referrals or jobs.
