First, call with hiring manager, followed by a more in-depth call with the same individual, before a final call with another senior member of the team. Overall, I found the people I spoke to and the recruiter very helpful, responsive, and they all had great questions for me during the process. There was a big focus on case problems. My only minor frustration was the timeline, as it felt a little like I was strung along for several weeks just to get a 'no.' They were professional throughout the whole process, so I wouldn't close my door on trying again, I'd just hope for a more efficient second time.
