I had a first phone interview screening. The questions were pretty basic about swap c++ function pass by value or reference, state machines. One question to find a fixed pattern 1 0 0 1 0 in a sequence. and the hardware that would detect it.

There was no phone screen, this one engineer called me over for a on-site interview. Less than 45m into the interview the guy lost interest, kept talking about what they do and whatnot. The interview was a complete waste of my time.
