Applied through LinkedIn and the recruiter reached out to me. In the initial call recruiter discussed about my past experience and skillset. I had to follow up with the recruiter to setup the 1 hour tech assessment. The tech assessment was straight forward and the interviewer asked me to implement a local datastore that supports multi level isolated transaction. I was able to implement 90% of the feature except for a one line bug where I was not making a deep copy of the underlying data structure. The interviewer was not very responsive through out the interview. 5 days later I get a generic email saying at this point they have decided to move with another candidate and for the feedback they highlighted that my skill set or experience were not a fit for what they're looking for in this particular role. That was literally a WTF moment for me. I would expect proper feedback from them in case they are rejecting a candidate after doing a tech assessment with them. Typically other companies send out this sort of generic message during the resume review phase. My sincere request to recruiter please share adequate feedback in future or else don't waste anybody's time by inviting and rejecting a candidate for a tech assessment saying their skill does not fit the role.

The interview process consisted of an initial recruiter screen followed by a technical phone interview focused on data structures and problem-solving in Python. The onsite loop included 4 rounds: one coding round (medium LeetCode-style problem), one system design round focused on building a scalable ML data processing pipeline, one backend/API design round, and one behavioral round. Interviewers emphasized real-world problem solving, tradeoffs, and communication. Overall, the process was structured and aligned with large-scale distributed systems and ML infrastructure.
