What's the Most Embarrassing Thing That's Happened to You in an Interview?

39. Never anything really embarrassing but I don't have a good record on phone interviews

The first phone interview I ever did it became painfully clear that I wasn't what they were looking for.

The second was for a purchasing job and the first question was about a "complex procurement". I was caught flatfooted and it was obvious. I had this iPad in front of me but a quick google search wouldn't have helped. I found the answer several days later but it took some searching and reading. I think they lead with that because they already had someone in mind to take the job but they had to go through the process (public sector). The next day I asked my experienced basically mentor (he'd been doing this for over 30 years) and he was dumbfounded as well, "Why in the hell did they ask THAT?! That's beyond my level of needing to know that".

Side note. Ever had an interview with someone who's blind? Those Braille note takers are some clacking distracting things I'll tell you. Longer story there. Toughest interview I've ever had (and I've had many). Got the job. 295 people had applied for it.
