I submitted my resume on their website and heard back from HR about 2 weeks later. There were two phone interviews and a 2 hour onsite interview. All communication following their initial contact with me was very prompt, and phone interviews were all on time. Everyone I interacted with was very helpful and pleasant, and as I was coming from Google we had a lot in common. I think having Google on my resume was what helped me get a response, as I didn't have much relevant experience (I'm a recent college grad).
