Interview process was smooth. There were 1 hiring manager and 3 rounds with System Design, Leadership and Team. Its bit unprofessional after going through 4 rounds, automated mail of rejection is received. Its responsibility of the organisation to provide detailed feedback what went wrong and what didn't workout. After following up with recruiter multiple times and assurance never received the feedback. Please hire AI bots if the mechanism is so automated. Its disrespect to the person who spent time for interviews and went so far.
