Hittite Microwave interview questions

Was referred to this "prestigious" high achieving company by a former colleague. No particular position was discussed prior or during the on-site interview (which in hindsight should have alerted me). It was really an attempt to de-brief my knowledge of their COMP who I worked for. They never even offered to reimburse my (small) travel expense. Yankee ingenuity and frugality all wrapped up in one I guess.
