What was the most intriguing question you were asked during an interview?

What’s your favorite snack?

How would you build a search engine fir the hidden web (all sites behind tor, logins, captchas etc)

Why do I want this job?

Which isn't unusual, but was in context where I was applying at a retail sports clothing store with a degree in engineering, because I had too much free time on a few weekdays. Ironically I outlasted many generations of turnovers for most of the fall/winter, and finally quit from rushing to get there on time after my day job and excessive parking tickets.

"When did you last fail your colleagues really badly and what did you do to fix it?"

Saying "I don't think I ever fucked up really badly" was not an option, and the interviewer clearly told me "listen, I have to fill this form and it asks this". So I started making up bullshit answers, but of course I didn't want to make up something so bad I would fail the interview. And every time, the interviewer would say "hmm, but that is not really a big fuck up. What else do you have?".

Interviews are weird. Makes me think that when a company behaves like this, I should just tell them that I am not really interested anymore. But usually when you apply somewhere you want the job, right?
