I applied through a recruiter. The process took 6 weeks.

I was approached by the recruiter and went through four remote interview sessions. First was about my past experiences, motivation and also about the company & product. The other were technical focused on programming (API design), distributed system design/optimisation and database systems. All the interviewers and recruiters were very professional, patient and helpful, and the meetings ran in a pleasant, low-stress atmosphere. This is a top-quality recruitment process. It took a long while to get the feedback, but it was all happening during year-break/holidays season, so I consider the wait time justified.

Given a task to perform - describe a distributed system design & reiterate on how to improve its performance.
