Applied online, received a response from HR the very next day to schedule a time to chat with her (I was pleasantly surprised by the promptness), then I had two hour-long technical interviews with engineers.

The questions asked were very reasonable, and the whole experience was very positive and even educational (after I solved the problem during the first interview, the interviewer explained why he asked that particular problem and how it is relevant to the company's product).

Algorithms related to databases (surprise!) and data structures.
