I got call from recruiter ..never talk to such recruiters before. they have wasted lot of my time. In first call they set up meeting with me for particular date/time and never called me and said sorry we forgot and do not have your number..So again they set up another time with me and there also I planned to attend call ...again i never got call from recruiter ..i message them and they said we were busy in other call...finally they call me after my time was wasted and i did not find them flexible enough they were giving weird and incomplete answers ..I realize at that time.. i do not want to go for another round luckily they did not call me for another round..Good luck !!!

4 Rounds of Interviews. Hiring manager, then technical, behavioral, and system design. The questions were typical that I can tell for a senior role. After the final interview, I was ghosted by the company and they never followed up with me. So thanks Zendesk for caring about wasting my time and never following up with me. Very unprofessional
