It was an on-campus interview with two engineers for an internship in their infotainment group. They asked a few behavioral questions for 30 minutes, then they gave me a coding test on paper. The coding test was 15 minutes long and had 15 free-response questions, of which you had to answer 10. It was mostly conceptual questions about OOP in C++, and also some lower-level stuff.

Tell about a time you had to take leadership while working in a group.
