first call with the recruiter second call with a peer or another colleague third call with your hiring manager panel with a usecase where you have to present for CFO. This part is very challanging and most candidates fail.

I had three interviews. The third interview was a 20 minute presentation infront of a 4 person panel. Followed by QA afterwards. My biggest issue was they asked a lot of work of the applicant. The company should atleast have the decency to provide feedback afterwards. All I received was a generic email saying I didn't receive the position which didn't even come from an actual team member. Personally, I don't feel that is acceptable when you make it the last round of interviews and have to do additional work for your interview.
