Total 3 rounds. 1. Technical interview with talented data engineer. overall based on data structure. 2. Technical interview with another talented data engineering person mostly based on resume and technologies from resume 3. CTO round - Firstly rescheduled from morning to evening because cto was busy. At evening he joined 5 min late and clearly he just woke up from sleep. He was not at all interested in taking interview from the first word he said. He didn't even read my details before joining interview call and in 12 minutes we finished interview with clear understanding of rejection.
