The interview process at Datadog is very complete and clear.

There is a first interview with HR. In this first interview, we should explain what we are looking for and see what Datadog can offer. The main goal of this first step is to align expectations on both sides.

Then there is a technical live interview. Basically, we need to solve a LeetCode exercise. Before that, Datadog sends materials to help the candidate prepare and train.

Then there is a system design interview, where you are asked to design and discuss an architecture. Here you should show your skills in architecture, design, and problem-solving.

They asked me to solve a medium-level LeetCode exercise.
