good questions

“What do you mean by XX?” This phrase is exceptional, simple, and under-used in my opinion.

I’m no longer content to ask, “What do you think about X?” Instead, I ask, “How did you come to believe X?”

a great question to ask a company when doing dilligence:

"What's a feature request that you get a lot, but that you will never build?"

Helps understand where the focus of the team is
