I assume they wanted more than a DFS or BFS or similar with loop detection? The teleports sound like a fun twist, although I'm not sure they change that much since from a graph perspective presumably they're just another edge?

Yeah, but does that kind of problem really exist on a regular basis for a test engineer on that team? I doubt it.

It's probably not that relevant to the job, but as far as weird questions go it's not too bad. It's presumably not leetcode hard, basically.

Actually it was literally a hard leetcode question! The other 3 were 2 medium and 1 easy. I can work out easy and medium leetcode answers from first principles in an interview setting, usually. I can't with hard ones tbh.

But ultimately it seems very divorced from reality of what I do, which is TestOps (building out CI pipelines, reporting, test infra, etc...).
