Received phone call following application to schedule a phone interview. Phone interview asked about previous work and asked the palindrome question. Immediately got request for a face to face interview. At face to face interview I had a linked list question, a riddle, and the piano tuner question. Also they asked about group skills and general coding questions.

Applied through the instructions on their website. A day later, I received an email from the company's HR rep who asked a few extra questions and then scheduled a phone interview for me with the engineers. Phone interview was very straight forward, and a half hour after conducting it, I was invited for a live interview at their office. This was a bit trickier, but still straightforward.
