Applied via internal referral. Initial contact from recruiter took 4-5 days (after my follow-up). Initial phones screen was scheduled, then cancelled, then repurposed to a "2nd round phone interview". 2nd round phone interview was a no-show (by interviewer) and had to be rescheduled 5 days later. Once moved on to in-person, prep call was provided by recruiter to give compensation details and interview advice. I also learned during this call that a writing assignment was supposed to be completed. This was the first I'd heard of it so the recruiter apologized and asked if I could complete it ASAP. In-person interview was 9am - 3pm (5 interviews and a lunch) and solely consisted of behavioral-type questions. Hiring Manager was "totally advocating for [me]" and was "very excited to get [me] onboard". A 30-minute follow up call was scheduled a week later with interviewer #2 from my in-person cycle. Asked similar questions to the in-person interview and was very curt. I was notified within an hour that I was not selected. Overall, very disorganized (cancellations, no-shows, assignment miscommunication) and felt confusing as I was receiving mixed signals (hiring manager wanted to hire me, "other" interviewer didn't). Long process and lots of preparation required yet "company policy" is to not provide any feedback so I'm left with having no idea why I wasn't selected.
