they gave 1st take home assignement related to charpoint problem, 2nd roud discussion on take home assignment, 3rd round deep dive ML, data engineering questions. 4th round discussion with a AI leader in Europe. 5th Round in person discussion with VC in data science of India. After clearing all rounds, HR called and said contgratulations and discussion about pay scale, I did small negotiation, she said will come back after internal discussion. Then ghosted me for 1 months giving different kind of excuses and finally got rejection email. Such a pathetic interview experience.
