I applied through a recruiter. The process took 3 weeks.

It was a good interview process that is transparent and laid-back. There were three main phases after the first screening:

• A generic interview with other potential teammates.
• Coding.
• System design.

There was good follow-up by emails from the recruiter.

Let's say you have a customer with 100 servers, with each server sending 10k metrics with a timestamp and a value every 10 seconds. We want a system in our datacenter to store the data and to be able to retrieve it for reads.

Each metric consists of a timestamp (unix timestamp 64 bits), which can be second resolution or a separate year, a floating-point value 64 bits, and an identifier string that is 85 bytes. How would you approach and think about this problem? Let's discuss.
