      Software Engineer Interview

      Jun 10, 2024
      Anonymous employee
      Toronto, ON
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied online. The process took 3 weeks. I interviewed at HackerOne (Toronto, ON) in May 2024

      Interview

      The interview process was a smooth and efficient journey that lasted about three weeks. It started with a friendly 30-minute call with the recruiter, who gave me an overview of the opportunity and what to expect. After that, I had a 60-minute chat with the hiring manager, where we delved deeper into the role and what they were looking for. Next up was a 90-minute technical screen with a senior software engineer. This part was pretty challenging but also engaging, as it really tested my technical skills and problem-solving abilities. The final stage involved two separate team interviews, each about 60 minutes long, with different groups of team members. These interviews gave me a good sense of the team dynamics and culture. Throughout the entire process, the recruiter was fantastic, giving me feedback after each round and keeping everything transparent. Everyone I met was super nice, and the interviews felt more like conversations than formal assessments. Overall, it was a positive and rewarding experience.

      Question 3

      •The system design interview required designing a system to solve a given problem, explaining the solution, and answering follow-up questions. Nothing overly complex, and all the interviewers were lovely and supportive throughout the process.

      Average interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at HackerOne (Austin, TX) in Aug 2025

      Interview

      The interview process was very high quality; from the very beginning, the recruiter and hiring manager were very communicative and answered any question I had during the process. Each individual had genuine interest into "who you are" and made the interactions feel more like a conversation rather than an interrogation. The technical interview was collaborative and fun, challenging you to think deeply without the typical "gotcha" questions that are difficult to complete. After having done quite a few interviews through my career, I can confidently say that my interview experience at HackerOne was one of the best.

      Interview questions [1]

      Question 1

      I can not disclose questions during the interview, but preparing general behavior questions as a starting point would be my suggestion.
