Epic Software Engineer interview questions

Talked to someone on the phone, then had an online technical interview, then finally visited the campus for some more interviews. Kind of a lengthy process, but none of the questions were too difficult.

I applied online. There was a behavioral screen followed by a coding challenge consisting of two halves. The coding challenge lasted 3 1/2 hours long. You were watched by an online proctor through your webcam for its entirety, pretty creepy to be honest. Also, they take control of your computer and disable all external ports. The first half's objective was to learn a fake programming language and answer questions at the end of each section. I might be stupid but I honestly thought the documentation and how the language was constructed was very poor leaving me confused half of the time. The second half consisted of four standard programming languages. The text editor is just a plain HTML text box. No documentation is allowed. The proctors didn't let me use the restroom either.
