3 rounds - 1st was a phone screen with hiring manager, 2nd was a webex with a manager from the team, 3rd was a webex with another manager. The 1st round the hiring manager he never showed - some mix up with HR. No apology or anything. Had to be rescheduled. After 3 rounds and couple weeks passing, I received a very informal rejection email after my follow up. I asked for any useful feedback, but no response at all. Not a good feeling from this company. The initial dropping of the ball on round 1 and no feedback after going through 3 rounds rubs me the wrong way. I'm totally fine not working for this company.
