      Staff Engineer Interview

      30 Aug 2021
      Anonymous interview candidate
      New York, NY
      No offer
      Negative experience
      Difficult interview

      Application

      I applied through a recruiter. The process took 3 days. I interviewed at Datadog (New York, NY) in Sept 2020

      Interview

      I was approached by a recruiter from DataDog. I talked with her and then with the hiring manager. They detailed how the hiring process would be five hour-long interview sessions, one of which would be a live-coding interview, as well as a take-home coding project. When asked if I wanted to continue with the interview process, I said "no," explaining how their interview process sounded tedious, full of "busy work," and that I didn't want to subject myself to the stress of it. They responded by saying that they'd drop the take-home project, and asked if I would reconsider. Reluctantly, I agreed. Three of the interviews felt like they went well. One interviewer no-showed on me...that should have been my first clue as to how correct my original gut instinct was. But on the strength of the first interviews, I continued on. The live coding exercise allowed me to pick a language, and code up a solution to a lightly-defined problem. I admit that I wasn't on my A-game that day; but in all fairness I'd tried to stop the interview process long before it began. Of course, the response was: "We met as a team and debriefed and, unfortunately, we've decided not to move forward with an offer. It came down to coding skills and technical breadth that we need with such a lean team." Like I said, I know that I wasn't feeling at my best, and didn't do as well as I'd hoped. That'll happen during a pandemic when you're working 60 hour weeks at your current job, AND squeezing in 5 more hours just to be judged by people. I would have thought though, that the 900 answers (at the time) that I'd posted on Stack Overflow or the two books I've written on database engineering would have made up for that. Guess not. The bottom line is that I was a passive candidate. I was asked to interview, and clearly stated that I did not want to. After some coercing, I reluctantly agreed to interview anyway. Once I was in their interview pipeline, I was treated like an applicant...not a recruit. At no point did anyone really make an attempt to sell me on wanting to work at DataDog. And to top it off, I felt more than a little insulted on the way out. In re-reading what I have written here, the number of red flags which came up during this process was astounding. The only good to come of this, was that I learned a new respect for my gut feelings.

      I applied through other source. I interviewed at Datadog in May 2025

      Interview

      I applied for the staff engineer position and got rejected the next day. It was too quick. I believe the rejection was an automated one. Most probably they have already hired somebody. But haven't taken the post down yet
