      Software Engineer Interview

      Jan 10, 2017
      Anonymous Interview Candidate
      San Francisco, CA
      No offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 3 months. I interviewed at HackerOne (San Francisco, CA)

      Interview

      High level: - 1 phone screen discussing culture/philosophy/tools - 1 in-person interview with lunch, 2x1.5 hour pairing sessions, 2x1 hour social/culture discussions Low level: - Emailed company, got reply in a week about interest in continuing further - Back/forth 2 weeks to schedule a phone screen due to slow responses - Phone screen went as discussed in high level. HackerOne was open and communicative during interview - Back/forth 2 weeks to get confirmation about next stage (in-person interview) due to slow responses again - In-person interview went as discussed in high level. HackerOne was open and friendly during interviews - Pairing sessions involved adding features to existing codebases (mostly me driving) - HackerOne asked for references a few days later and I handed them over promptly - Followed up 3 times for 3 weeks after handing over references (there were responses to each of the follow ups with minor progressive movements) - Received request for phone call 2 weeks later (last follow-up was during Christmas/NYE week so potential reason for delay) - Turned down via phone call

      Average interview

      Application

      I applied through a recruiter. I interviewed at HackerOne (Groningen) in Sep 2025

      Interview

      I received an invitation from a recruiter to apply. The interview process consisted of three stages: a cultural fit interview with the person who would be my manager, a live coding technical interview, and a system design interview.

      Interview questions [3]

      Question 1

      •The cultural fit interview was focused on getting to know each other and discussing experience, values, expectations... etc.
      Answer question

      Question 2

      •The technical interview involved solving a LeetCode-style problem through live coding.
      Answer question

      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.
