Had a code test, followed by a phone interview, and a full day of tech interviews.
The code test questions were the same as mentioned before: sorting strings and numbers in place, and a data center sync problem.
The phone interview was okay; it was a chat about past projects and simple questions.
The onsite questions were tricky and covered data structures, algorithms, string matching, tries, etc.
