LinkedIn interview questions

Was contacted by a recruiter through LinkedIn (very meta) and given two weeks preparation. The interviewer I was scheduled with wasn't the one who ended up interviewing me, and instead it was someone who had a very tough time speaking English and explaining the problems. I solved both questions, but it took a long time before I would understand what he meant when trying to explain them. This chewed up a substantial chunk of the interview time (for example, it took ~5-10 minutes to even get to the collaborative online editor because I couldn't understand the letters he was pronouncing in the URL).
