I got these in a dropbox phone interview:

>You have two buckets, one holds 3 litres and the other holds 7 litres. How do you get 5 litres exactly if you have nothing to measure with?

>If two painters take two hours to pain two walls, how many painters would you need to paint 12 walls in 18 hours?

>My special skill is that I can throw an M&M into the air and catch it in my mouth, what is your special skill?

I also remember seeing someone on Glassdoor claiming they got this question off them:
>you have two children, aged 5 and 8. Explain the concept of prime numbers to them
