I don't find it that strange for someone to claim they never make mistakes. However, I would press for details as to why they never make mistakes. They probably don't take many risks, or work on the same or repetitive stuff for a long time, or don't consider "forced errors" mistakes, like a client gives you a bad spec and you implement it and they get mad. You could consider that you made a mistake in not pressing on the bad spec, but you could also just consider it a "forced error"--you didn't "make a mistake" the same way a chainsaw doesn't make mistakes. They might also consider an unreasonable deadline a 'forced error' or some sort, where they don't consider themselves to have made any mistakes if they indicated insufficient time and cut corners under 'duress'. Someone might take issue with that and call that a mistake, but it actually seems to open up an interesting line of questioning as to why they don't believe they have made a mistake.

It's either delusional or naive to think you never make mistakes. Everyone does.
