      Software Engineer - Front End Interview

      Sep 26, 2024
      Anonymous employee
      Paris
      Accepted offer
      Positive experience
      Average interview

      Application

      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!

      Software Engineer - Front End Interview

      Jul 7, 2024
      Anonymous interview candidate
      Lisbon, Lisbon District
      No offer
      Negative experience
      Difficult interview

      Application

      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.
