I had a weird interview once. I used a common C# shortcut and the dev asked what it was....I explained....he said it would never compile. The whole interaction was really awkward and he was being kind of an ass about it. I believe I asked "Would you like me to write it out so you can understand?". Frankly, at that point I was pretty annoyed. This was in front of 3 devs. He just sat there quietly, so I did rewrite it anyway in the complete syntax. I ended up getting an offer but declined. As I was walking out the devs were on a computer trying to see if it works lmao. I would always suggest not to get to upset, but I don't see why you can't fire back at them.
