Ubiq (YC company) interviewed me with an 8 hour assignment that had ridiculously challenging requirements. It was very fun because there was no way any normal human could do it in 8 hours... but how far could I get? And they paid me for 8 hours working on it.

I felt this was good. I got paid and it was a fun challenge. It also obviously wasn't "actual work," but even if it was, I was getting paid, so why not?

I don't think it would have been out of the question to say I was too busy to dedicate 8 hours either, but in my case I had the time.

Overall it was an excellent experience.
