Very haphazard. I was contacted via LinkedIn. The initial person who contacted me was very pleasant but was not able to answer even the most basic questions about the position. I was passed on to another recruiter, who was disinterested and largely seemed to use automated processes. I had no conversation with the recruiter prior to the interview and there was no advice or information provided at all other than the name of the interviewer. When the screening call started it became quickly apparent that it was not the role I had been contacted about but proceeded anyway and the call went well and got surprisingly technical for a screen call. After the call I heard nothing, but eventually received a generic rejection from another recruiter about my 'application' to another different role entirely. I tried to follow up but they were not remotely interested.
