You're asking the wrong question.

For all software businesses there is only one question to ask candidates: "Can you help us ship working software that solves the problem of our customer"

What I can tell you is that there are a number of books written on this subject if you need help identifying the correct interview questions to ask.

But this question does not really tell me anything. It only has one possible answer, which is "Yes!"

If I had a magic truth-detecting wand, it might be a good one, but in practice, candidates may be lying or honestly overestimating their ability.
