Once I got really detailed feedback from an interview for a job I didn't get. It really took me by surprise! I didn't even have to ask.

It was quite interesting too because the things they'd inferred about me - stuff that I had understood or not understood - were just plain wrong. I didn't get everything right, but some bits I did understand fine, they thought I didn't.

I'm not sure what to take from that, other than that it's not about knowing stuff, it's about convincing someone else that you know stuff.

Also I'm about to do a hardcore leetcode interview. Wish me luck. (I'm probably going to fail; I'm pretty great at programming but only average at leetcode.)
