My interview began with a recruiting company as the position was contract to hire. Although the interview process isn't over, I can say that the company is really digging into my skill level and background; requiring 2 referrals even prior to the second interview, requesting written summaries of how I manage projects, etc.
The first interview was with the recruiter, the second with the PMO manager. The questions were vague, which forced me to re-question everything asked. The manager asked for a written summary of how I would handle running an applications project, although, I had already explained, in detail, how I had done that in the past. This makes me believe the manager isn't detailed or direct enough which is vital for PMs. (BTW, this request was asked of me by my recruiter PRIOR to my having any conversation with the hiring manager - I declined the initial request until I had a chance to chat with the hiring manager in order to get a better feel for what he wanted.)
The rate/offer from the recruiter is extremely low in comparison to jobs of equal skill levels. This, however, may have nothing to do with the FTE salary ON offers.
For this particular position, I would say the level of interviewing is extreme and unwarranted.
