Went through a phone interview with the CTO. He mentioned company moves fast and if the team feels I was qualified then they make offer within 1 day. Later I was called for onsite interview by the HR. Company was very accommodating for my vacation schedule but they had to plan at the last minute. 4 Engineering(ML/DS) interviews and exit interviews with CTO and HR. All back 2 back 45 mins each. No breaks :) Oh did I mention... the company moves very fast.
