A recruiter contacted me after I completed Level Three of Foo.bar.

There was an informal chat with the recruiter, after which I had a technical phone screen.

The phone screen question was of medium difficulty, but the interviewer had a thick accent, and I couldn't understand what I was being asked. I spent over half of the interview trying to clarify what he was saying, so I don't think he was left with an accurate appraisal of my ability.

Nevertheless, the overall experience wasn't bad. I learned some valuable things, and I'll apply again in six months or so.

It pertained to graphs (DFS, BFS).

I will keep the full question confidential, but it was within the range of what I was expecting.
