The interview process started with an initial "take-home" coding challenge. Following that were three technical phone interviews. Each interview was about 45 minutes long. The last two interviews were conducted back-to-back over a span of about 2 hours.

The process ended with a final 45-minute video interview, which was conducted over Google Hangouts. This interview involved a mix of technical and personal questions. My specific video interviewer said up front that the interview would focus more on technical questions, but your mileage may vary.

I was asked not to share details about interview questions, but topics covered included:

• Bit-level representations of integers
• Structures for efficiently storing strings
• Building a simple parser/interpreter
