I was referred by a friend and then contacted by an internal recruiter. I chatted with him for a while, and a phone interview was scheduled.

The phone interview was fairly standard. I had told the recruiter that I was most comfortable interviewing in Python, or C++ in a pinch. This apparently didn't get passed along to the interviewer, who asked me to code some stuff in Java. I was also asked about my experience, although it almost seemed like he was waiting for me to say the right magic word in the answer than actually listening about what I'd done.

I was told by the recruiter that they'd like me to do more interviews, and that those would be coordinated by a different recruiter. For the next three weeks, this recruiter kept telling me he'd be in touch "soon." That never happened, despite me repeatedly reminding him. Then he disappeared on vacation for the holidays. I don't know if he was being lazy, or what. I still haven't been contacted, or told that I'm no longer being considered, so who knows.
