I had a telephone interview. As soon as the call connected, we dived right into the questions she had for me, with no small talk or introductory questions. I think this was to ensure we had enough time to finish the solution.

I was asked to solve one problem on data structures, which was based on a real-life situation. I wasn’t able to solve it, but the interviewer was kind and tried to ask questions that would lead to a hint. In the end, she asked if I had any questions and patiently answered them.
