This is based on my overall experience. I'd gone through the entire process and made it to a final interview. Was feeling good about the process. The hiring manager was about 20 minutes late to the first team interview and asked some questions that set me back because I had to review information I'd already shared and I didn't finish my presentation. Continuing on, the rest of the interviews were fine but I didn't get a strong sense that there was as much of a fit as there was when I first arrived. It took about 3 weeks and a few check-ins from me with the recruiter to hear that I hadn't been selected (not a surprise to me by this time) but they really wanted me because I would be a great fit for another group. She asked me to give her a "few days" and she would get back. It really was an extremely positive conversation that left me very hopeful. So it was interesting that I never heard from her again. She never returned the email follow ups I sent. The following year, I had a great candidate for her for a similar position I'd interviewed for - I felt based on the process I'd gone through I had a better sense of what they were looking for. Incredibly, she never returned that email either. Very sloppy. Would never want to work there based on this experience.

A very informal process. Short call with a recruiter and then a meeting with the hiring manager. Only asked one question during the interview. No communication since the last round of interviews.
