Other Front End Developer Interview Reviews for Datadog
I applied online. The process took 2 months. I interviewed at Datadog (Paris) in Sep 2024
Interview
First step of the process is to select candidates with a generic role in mind:
1) short recruiter interview
2) 1h with an engineer - 30 minutes about candidate's experience + 30 minutes simple coding test
3) 1h design interview with an engineer
4) 1h frontend coding test with an engineer
5) 1h more in-depth coding test with an engineer
6) 1h experience and values interview with a manager
If you make it through all of this and get selected, you then go through a few team maching rounds (30 minutes calls) to find the best team for you and finally get an offer.
Recruiters and coordianators were very responsive and helpful through the whole process. You get to meet a lot of different people which is very good to get a overview of the company. Great candidate experience overall!
I applied through a recruiter. The process took 3 weeks. I interviewed at Datadog (Lisbon, Lisbon District) in Jun 2024
Interview
I'll preface this rant with a bit of context: I've been in the industry for more than a decade and worked on pretty big products, most of which have a nation-wide user base.
I had two technical interviews: the first coding one felt more connected with the interviewers and more engaging. While we haven't had a *match* per se, I had a decent understanding of how I haven't fully met their expectations.
The system design one, however, has been a very deceiving experience: while I thought we had a good conversation with the interviewer and I haven't felt challenged in any way neither by the initial formulation of the problem nor by the following questions, it turned out that I failed, which was a total surprise.
Furthermore, while my coordinator suggested scheduling a feedback session, they didn't follow up on that and I haven't had a chance to hear what exactly went wrong.
While my ego feels hurt by this rejection, I totally understand that things like that happen all the time and it's really hard to find an engineer with a certain skillset _and_ a suitable vibe. I'm just sour that I felt dehumanized by the whole process.
Seems like the company is going through a major growth phase and their HR brand does more harm than good creating excessive stress on the hiring pipeline.
