Several phone interviews, followed by on site interview. I really liked the hiring manager. I got the impression that he was one of the most honest and empathetic writing managers imaginable. I was treated very well throughout my interviews and had ample time to meet the team and ask questions. A very pleasant experience. I was disappointed, however, that the company offered no sort of follow-up after the extensive time I spent interviewing. It's common courtesy to at least send a letter of rejection if you pass on a candidate, but ghosting applicants who interview is unprofessional.
