The interview process starts with a recruiter call. I went through a referral and received a call the next day.

Typically, there's a tech screen over Zoom. Once that's completed, a take-home test follows, which takes about 4-6 hours to finish. I heard back from the recruiter within three days and was scheduled for an on-site interview.

The on-site interview included:

• One coding round (front-end focused, reflecting day-to-day tasks at Datadog)
• One system design round
• Several conversational interviews

I didn't perform well in the system design round and knew I wouldn't receive an offer.

However, everyone was incredibly friendly. The recruiter, Sophie, maintained consistent communication throughout the process, assisting with scheduling interviews and providing progress updates. All the developers and managers I spoke with expressed pride in the company and genuine happiness working there.

Overall, it was an enjoyable and excellent interview experience.

The tech screen involved parsing a JSON object from an API into a specific format.

The take-home assignment was an OS load manager exercise that takes 6-8 hours to complete.

The coding round at the on-site was also a JSON parsing exercise.

If you have been doing JavaScript coding for a while, these should not be difficult.
