Ericsson Test Engineer interview questions

First off let me state that this interview was for a Co-op (work experience) position. I applied via Ericsson's own Co-op placement site. I heard back from them within about 3-4 weeks and got summoned for an interview. The panel consisted of one HR person and one engineer. The tone was relaxed, a lot of the questions and chat was general. The environment was professional but at the same time relaxed. The interview lasted 45 minutes and they rang me the next morning to tell me i got the position
