      Senior Software Engineer Interview

      6 Oct 2022
      Anonymous interview candidate
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 1 week. I interviewed at HubSpot in Oct 2022

      Interview

      The experience was more or less what was talked about in these reviews. You're given a screening process where you're given an array of data through a API and asked to post that data back to another API route sliced up and restructured. After you pass that there's a final interview with 4 rounds. 3 rounds are technical interviews. 1 system design question and 2 programming questions. The last interview is a behavioral interview with the hiring manager. Anyways I received pretty much good feedback across the board according to the recruiter, but I wasn't perfect in the systems design portion. But here's the kicker. They asked me about component design, not a full system design. And then they rejected me because I wasn't strong enough in something they didn't even ask me about. They even mentioned how I didn't mention i18n during the component design portion... I didn't mention it because that's part of a whole application design not a single component... They straight up asked me how I would design this single component they showed me. I don't know what they wanted from me. The recruiter told me that they haven't seen someone get such good feedback like that and not receive an offer. I was told that a position with another team could be found in a week or two, but I already had a few offers on the table so I went with one of those. So be wary with this interview process. Might turn into a waste of time like it was for me.

      The process was ok until the last step but once I got to team match round I was told there are no roles available. If no roles available then why waste candidates time? So much effort goes into prepping and the recruiter just went MIA

      Interview

      Single exam no human interaction. The exam was like a college test, something completely unrelated to modern field work. Seemed a bit off base. Definitely didnt seem like a realistic approach to finding real humans to fit for a company.

      Interview questions [1]

      Question 1

      Complete technical exam about solving programming algorithms.
