The interview process began with a technical phone screen with the hiring manager. We mostly dived deep into one of my projects on my resume and ended with a Leetcode (medium) question on DP from Blind 150. Then I had 6 rounds of interviews for the virtual on-site. Since I am a PhD student, one of the rounds was a tech talk followed by Q&A, and the other was the Bar Raiser, which only focused on Leadership Principles. All other rounds were technical, focusing on science breadth, depth, and coding. You should know your fundamentals for different ML algorithms, Transformers, and current GenAI techniques (pre-training, fine-tuning, post-training, prompting, etc.)
