      Product Engineer Interview

      8 Dec 2025
      Anonymous interview candidate
      London, England
      No offer
      Neutral experience
      Difficult interview

      Application

      I applied online. I interviewed at PostHog (London, England)

      Interview

      Several interviews including cultural, technical founder chats and a day long technical task (paid). Generally friendly and open though I found the technical task cared more about speed/progress than building the "right thing".
