I obtained an interview with on-site managers through a recruiter. This process included a video screening interview with the recruiter, followed by a request for an interview through said recruiter. The interview itself is medium-level in difficulty, asking for very detailed answers to scenario-based questions. My only complaint was the recruiter stage of the process. My initial recruiter either changed her name or terminated her employment suddenly in the middle of my hiring process, so I had to re-apply to come in contact with a new recruiter. They may have contacted me at some point regardless of my follow-up, as they may have been working their way through her backlogged clients, but this hiccup did significantly lengthen the time it took to acquire an offer. Overall the process is lengthier than previous interviews I've had, but average in question difficulty. They expect professionalism. I would recommend coming prepared--resumes printed, questions for the interviewer printed, schedule printed, etc. You need to know the position well and understand what makes you exceptionally qualified so you can bring it to the table during the interview process.
