A university recruiter contacted me after I had applied for an internship. She requested my latest transcript and resume.

I then had two phone interviews, followed by an invitation for an onsite interview in January.

The interviews were one-on-one and quite similar. They generally began by asking about my experience, then progressed to a coding question.

Two weeks after the onsite interview, I was informed that the hiring committee had rejected me.

The questions were on algorithms and data structures, like maps and trees. You need to know when to use different data structures in different situations and what the trade-offs are for using one over the other.
