The phone screen was surprisingly short, only about 20 minutes, focusing on my background and some general ML concepts. Then came the technical round where I had to design a ranking model for Instacart’s search results. Midway through, it hit me that I had just practiced a very similar problem on PracHub, which made me feel a bit more confident. However, the depth of the discussion, especially around metrics and cold-start items, was intense. In the end, I didn’t receive an offer, but it was a decent experience overall.

1 round of HR screen, 4 rounds of technical Technical: - ML alg knowledge - Live code - Leetcode style - Case study: they give you a case - Retro study: walk them through a past project

There are four round in total: 1 code (leetcode easy level) 2 ML concept (focus on fundamental traditional ML stuff) 3 ML system design 4 BQ and project NDA signed for last two rounds. But the recruiter will tell you the expected topic
