Interview
HM reached out. The first round reviewed my resume and focused on one project in depth. The final round included 5 technical interviews and 1 behavioral interview. The technical portion covered ML knowledge and case studies.
I applied online. I interviewed at Amazon in Apr 2023
Interview
One code question and several follow-up questions. The code is more ML-based instead of Leetcode type. Follow-up questions focus on understanding and implementation efficiency (computational time and memory, what if...).
