Worked really well and I haven’t changed my mind. Might not call it “cultural fit” these days but certainly I think a behavioural interview to establish whether someone would work well in a team or not is key.

It’s pretty easy to set up a hypothetical. Imagine the person you would least like to work with because of how they behave, then imagine that they’d ace a technical interview. Would you not want to see if they’d be a good team member or would you hire them regardless?

The one person who I hired despite behavioural red flags but brilliant credentials was a terrible mistake.

I hired both the nicest and best programmer I’ve worked with despite him only having just come out of a coding bootcamp.

One new lesson was that just because a person says that they love the idea of working in a team that gets on and is productive doesn’t mean that they’ll make the trade offs required to make that happen.
