This is a very time-consuming process. It takes a while before you hear back, and that can be very annoying. I would not interview with this company ever again.

It was smooth at first, but getting further requires more brainpower. I really have to think logically about the questions to answer them well. The key here is to be well-prepared before the interview.

Very slow to respond. I'm not sure what was going on here. It took several months to get a final verdict on the decision. I had to follow up several times and wouldn't hear back for weeks at a time.
