It was a 45-minute or 1-hour on-campus interview.

I came in, and they asked me the usual EA questions: What were your past projects? What video games do/did you play? What do you know about EA?

Then they asked me the interview question, which was to 'print out all the nodes at each level of a tree'.

So, I explained what I was doing and did it. The interviewer was annoyed that I was explaining stuff to her instead of actually coding. She didn't say anything the entire time except yes/no.

After I coded it, my solution worked, except I didn't erase one unneeded line. She spent 5-10 minutes lecturing me about that line. Are you kidding me?

Print out all the nodes at each level of a tree.
