1. Phone screen with a recruiter (within a week after my application)
2. Technical phone interview (took about 2 weeks from the phone screen)
3. Onsite interview (took about two more weeks). This process was about 5 hours and involved meeting individuals from different groups.

They paid for the flight and accommodation, as I had to fly from a different state.

Interviewers were good and knowledgeable. The interview process was a good experience. However, I think they favored their own design or solution approach. My thought is that they can't expect a candidate to give the exact same solution without having the same level of inputs, system knowledge, exposure, and time. :)

Some were puzzles.

Many of them were database-related questions, covering technical, design, or problem-solving aspects.
