It took 4 months to get to the phone screen. There were 2 rounds of phone screens. The onsite interview involved a "panel" of about 10 people across approximately 5 sessions, each lasting about 1 hour.

The scary part was when I was asked to present the way of testing a random generator. I had knowledge of statistics; it was one of the major classes at my university. I presented a method for testing the statistical model of value distribution. The person who asked really believes that if numbers are not equal, the generator works properly. Anyway, I received feedback that I needed to work on my test methodology skills, and I did not get an offer.
