Once went for an interview for a senior web developer role. The first interview was a coding test ( not a problem, been coding for years and know I can do it). The company boasted that it supported pair programming.

I was sat at in an open plan office In front of a machine and given a question sheet of 10 code questions/puzzles and asked to solve them. Then out of nowhere 5 other senior devs appeared and stood behind me and proceeded to comment /question every single line I typed (so no pressure then).

I did questions 1-5 (fairly easy tbh) but all the devs behind me critiquing every single line started to drive me crazy so I asked if it was normal for them to interview this way and was told 'yes' and that after a year of trying to find someone they had been unsuccessful.

I told them that I wanted to leave the interview at that point; I don't mind my code being critiqued just prefer it when I've at least finished the line. Forcing you into a pair programming scenario in the interview really didn't feel right.

To this day (2years later) I still see ads for that very same job
