I was recruited via LinkedIn. I had a good informational call. I was then passed on to a recruiter who I also had a great call with. I then had a more formal interview with the person who originally recruited me. All went really well as I think I was highly qualified for this role. The next step was a call with the head of the department. She was overseas traveling at the time and I had to speak to her at 9pm. Our video chat connection was awful and the whole time it felt like she exhausted from the day (as anyone who works hard would be at 9pm) and was annoyed at the fact that we had scheduled such a late call. I did not receive an offer after that call and I can't help but wonder if those circumstances had anything to do with it. In addition, I asked for feedback because the first few calls I had went so well and I never got any kind of response from anyone on the team.
