But I have been laughed at on a phone interview before. It was for a game dev job, and I was told by the recruiter ahead of time "They just need anyone with any game dev experience at all," so I didn't spend too much time studying for the interview. I had developed and released several full games, even popular ones, but they were all 2D Flash web games.

So I was completely unprepared for 30 minutes of being grilled on 3D graphics math and console development. I answered to the best of my ability, and could have done better if I hadn't been misled by the recruiter, but no, it felt like I was being toyed with by the interviewers (kept hearing laughter multiple times after I answered).

I got a different and (equally good) job in the industry and the company that interviewed me ended up closing down about 6 months later, so it worked out for the best anyway.
