Am not in the USA, Netherlands actually.

For my internship I first had a good conversation with the lead developer. After it was determined that I was a culture fit and didn't bullshit them, I got a small simple assignment which I had to do on a whiteboard. Later found out it wasn't really meant to figure out whether or not I could write a simple function, but more to see what my thought process was. Like, did I instantly start writing one big function that did stuff - or did I break the problem down into smaller steps.

Anyways, the interview for my second job (for a fairly big consulting firm) was purely focused on culture fit, and questioning about stuff I've previously made.

Third and current job was the same as the second - only on my initiative I came by on another day to check out what the other developers were actually doing and trying to help them out.

I don't think a test is really useful, if I'm not up to par (or they don't meet my expectations) either of us can decide to end the contract in the first month. This focus on tests strikes me as silly, especially in the USA, since you can just be fired for no reason anyways.

edit: I do have an (outdated) github repo with some code, but not much else.
