I had met a manager before applying and had a great conversation for about an hour after which they suggested I apply to another position there. I applied, had a coordinator schedule a call with a recently hired recruiter who called me the next day. We spoke for 15 minutes about standard boiler plate questions and ones I had discussed at length with the manager who I met before and statements which I went more in detail with the cover letter, interest statement, and hypothetical problem assessment sections. Nothing was out of the ordinary or difficult and it seemed like it went well overall. I knew the manager chat before which was longer and candid went very well. The recruiter who called said she'd get back to me by end of day. She never did so I had to email the coordinator the next week who gave me the news that it was a difficult process but that this position wouldn't be a good fit in the end. I asked for some more feedback as to what part was contentious 3 days ago and still haven't received any reply.
