This has bitten me in the past. When I worked at a certain company, you had to do a full 8 hours of whiteboard coding in order to transfer laterally. So I was permanently stuck in the team that hired me, despite having the best possible performance reviews year after year. All because I can't think very well when I'm anxious and someone is looking over my shoulder judging me. I can solve algorithm problems just fine when I'm left to concentrate.
