Entrevista
The Hiring manager contacted me on LinkedIn. The team seemed really excited by my profile and I had the first round of interview with the team lead. It was purely ML based questions and I was able to answer them all. For the second round they send me an online coding challenge, which didn't relate to ML, was more about datastructues and algorithms. I did decent on that challenge but didn't get a call for the next interview round.
I was assuming they would give more weightage to my ML skills rather than some optimizations I might have missed on coding challenge and was pretty disappointed to not hear back.

The technical round kicked off with a challenging system design question about creating a real-time product recommendation engine for Amazon. It required deep thinking and a solid grasp of machine learning principles. After that, I tackled a complex DSA problem on finding words in a grid using a trie and backtracking. Funny enough, that exact question was on prachub.com just days before, so I felt remarkably prepared. The overall process was intense but rewarding, and I was thrilled to receive and accept the offer afterward.
The interview process was smooth, and the interviewer was professional and friendly. It was online and took about 35 minutes. The recruiter will give you some guidelines on how to prepare.
