The interview process began with a brief chat with the HR recruiter.

This was followed by two 1.5-hour interviews via Skype, conducted back-to-back with senior members of the technical staff.

One interviewer was friendly and encouraging, while the other was fairly remote and uncommunicative.

After the interviews, there was a follow-up call with HR to verbally go through the offer. This was likely to gauge my reaction.

They were quite cagey about the specifics of the work, only mentioning "unspecified new Roku products."

Write C code to implement common systems programming tasks. The sort of standard thing that you should be able to do in your sleep. But it's harder to do online.
