I applied through an employee referral. The process took 2 months. I interviewed at Datadog (Paris) in Jun 2025
Interview
The interviews consisted of two stages.
The first stage was a coding interview.
The second stage included a coding interview, a system design interview, a values interview, and an experience interview.
Before each interview, there was a call with the recruiter, who described the upcoming interview and provided hints on how to successfully pass it.
It was very important to listen to these hints carefully. One of the most crucial aspects was to communicate thoroughly with the interviewer.
Interview questions [1]
Question 1
The design interview involved designing a system for a game where the user would visit a webpage and see a screen consisting of a 1000x1000 grid of tiles.
The user had to select a tile and color it using a color from a predefined palette. After coloring a tile, the user would be locked out for 5 minutes.
I applied through a recruiter. The process took 6 weeks. I interviewed at Datadog (Eu) in Jul 2022
Interview
Offer rescinded after accepting!
- 3 rounds of coding
- 1 design interview
- 1 manager interview
Obviously I spent a lot of time and energy to go through all the rounds and was quite happy after negotiating and accepting an offer. But after a couple of weeks they sent an email rescinding it citing "business reasons". To make it worse they didn't even have the decency to call and explain and simple "ghosted" me since. Very frustrating obviously.
