I have been contacted in late November to fill a screening survey. In early December I've been told that I progressed to the next stage which was a phone interview and to expect contact in late January. In early January I've been contacted to choose an interview date in late January. The interview only consisted of two algorithmic problems, one of which was easy (sum two binary strings) and the other was a bit difficult. The interviewer was generally friendly, but didn't offer that much help or hints.
