I was recruited through a contracting company through LinkedIn, who set up the interviews for me. Three sets of interviews split between 2 days: with the Principal Investigators, with the Division Administrator, and with the Research Manager and study coordinators. Each lasted about 30 minutes. I received feedback by the end of the day.

The hiring manager lacked personality and is extremely unprofessional. I followed up three times and have not heard back. The professional way to go about that would be to simply send an email stating whether they are interested or not instead of telling the person that they will certainly hear back whether it is a yes or no and then leave them hanging.
