The recruiter was professional and friendly. I would say the interviewing managers were not as pleasant. It's revealing when your interviewer is in a high-level clinical position and is unpleasant. You send in a follow-up, and at the minimum, even if you are not chosen, they can respond to your questions. Being responsive to an email means being courteous and professional; there is a person/human behind every interview. This is the worst company, and I am glad I was not selected for the position.
