Talked to a Hiring Manager on Linkedin and got the interview setup in a week. First I had the Phone Screen round which included a couple of LPs with a Leetcode medium style question using Trie DS followed by Resume Deep Dive and my PhD Dissertation. After 3 days received an email for an on-site rounds. It was around 2 weeks between the PS and the on-site rounds. 7 rounds in total: Presentation on a topic of interest, ML Breadth, ML Depth, Coding, Bar Raiser, ML System Design, and System Design with the Hiring Manager. Did well on all the rounds except for the coding. I had 4 back to back rounds on the 1st day without breaks and coding was the last of those, and my brain was exhausted talking thru all those rounds. My fault of not preparing mentally for this. But the interview experience was really great. ML Sys Des: Design Alexa with none of the known tech Sys Des: Design a System without any DL or Transformers ot LLMs based on my PhD Dissertation topic Coding: Leetcode Medium A lot of LPs. When I say "a lot", it's literally "a lot". Had notes for most of them prior to the interviews, but the interviewers delved so deep into each of those situations and answers that I felt overwhelmed for a few. Prep: Prepared answers for diff LPs Coding on Leetcode for around 75 problems System Design videos and blogs for prep on youtube ML Breadth concepts and FAQs from diff prep blogs
