Process
I applied online. The process took 2 months.
I went through a 5-step interview process:
- Two coding rounds
- A system design interview
- An experience interview
- A values interview
It's a thorough process, but it felt fair throughout. What stood out is that the coding questions were closely tied to Datadog's actual domain which is observability, rather than generic LeetCode-style problems. It made the process feel more relevant and grounded.
A special thanks to the recruiting team, who were helpful and communicative at every stage, which made a long process much easier to navigate. If you're applying, be prepared to invest time. But know that the process is structured and the people you interact with are genuinely engaged.

- 4.0Interesting job, nice people, limited growth opportunitySenior Software Engineer • Current EmployeeMay 18, 2023Pros: Very interesting set of problems to work on. Most teams are very nice and easy to talk to, mostly good company culture. Decent compensation. A lot of very talented people to work with.Cons: Only a select few get promotions beyond Senior Software Engineer. Once you want to get promoted to a Staff Engineer, you're told that for that position you have to work on large multi-team problems. However, you're not given time to do that because you're still a Senior Engineer and have to work on firefighting and regular stuff. Very disappointing for me.
