The interview process was very long. The first interview was with HR, the rest 3 interviews with product managers. All of the interviewers were men. I was asked to prepare a presentation about the biggest challenge I faced as a PM. I put time and effort in creating the presentation. I received an email an hour prior to the scheduled interview which stated that the interview will be cancelled. The week after that, I got another email informing me that the needs of the team changed and they want to hire a more senior person. It is disrespectful to treat candidates like this.
