The HR first contacted me, and explained about Trafiic.com which was essentially acquired by Navteq, and he set up a technical phone interview. The lady who called me just started shooting technical questions at me without explaining about the position or the kind of work they do. I was then scheduled to meet with 3 technical people for a "casual" interview - but guess what..the first guy who came in had a 2 inch thick bundle of technical questions. They also explained how people are expected to work longer hours and during weekends if required.
The Malvern campus looks really nice, but the attitude of this company is far from it's parent company based in Chicago - it has a small company feel to it. Also, the HR didn't even bother informing me that I wasn't selected.
