I was recently cold-called by a recruiter on LinkedIn who had seen my profile/resume. The position seemed to be a very good fit for my skill set so I replied that I was very interested. Within minutes we were talking on the phone and after a laundry list of generic technical screening questions, we move on to discuss my personal projects. The recruiter responds positively but keeps asking for deeper and deeper details, to the point that I'm basically reading him pseudo-code. He does the same with my work projects but I (somewhat clumsily) deflect implementation level questions because the code isn't my property to share.
Seemingly unsatisfied, he requests that I send him an expanded version of my resume including "every technical detail you can think of" about every relevant project I've worked on all the way back through my senior year of college (about 4 years of work). He mentioned how a similarly experienced developer had submitted 20 pages of such information and was asked for more. This is apparently an application requirement set by the position's manager. I said that it sounded like a lot of work but could get it to him sometime the next week.
After some time to process such a whirlwind, I think this is way beyond asking for examples of my skills/experience to evaluate my candidacy. Is this recruiter/manager trying to steal the fruits of my labor or am I just paranoid?
Update: I walked away from the situation. The answers brought up a lot of possibilities, none of which I want to be involved with. I'm going to ignore cold-calls in the future.
