First-hand accounts from people who interviewed at HackerOne.
Engineering Manager
It was a pretty standard interview process for an EM role. Started with a recruiter screen, then a chat with the hiring manager. After that, there were two 2-hour panel interviews, one focusing on tech and the other on delivery. The final step was meeting with the SVP of Engineering. HackerOne was really friendly and communicated quickly. The whole thing took about two weeks, but they were cool with speeding it up since I had another offer. They even gave me a verbal offer the morning after the last interview and had the paperwork ready that same afternoon.
- Can you share an instance where your manager provided you with constructive criticism? What specific area required improvement, and how did you collaborate with your manager on addressing it? How did this experience influence your approach to people management?
- Tell me about a project you've worked on previously.
- What technical decisions were made on a past project, and can you explain the rationale behind them, including the process and who was involved?
Software Engineer
So the whole thing kicked off with a recruiter chat, then I talked to the hiring manager who asked about my background and some behavioral stuff to see if I'd fit in. After that, I had to do a technical test on HackerRank for Rails. Then came a live pair programming session, which was pretty cool and tough. The last technical part was a system design interview about real-world scenarios, and then we talked about the offer. Everyone was super professional and helpful throughout, making sure to understand my background and getting interviews set up when I was free. The recruiter was great at keeping me in the loop and making sure everything ran smoothly.
- Tell me about a difficult yet interesting problem you've tackled in past projects. What was your strategy, and what insights did you gain?
Product Security Analyst
The interview process at HackerOne was pretty smooth and laid out well. I went through three rounds total. First up was just an intro chat about my background and to ask questions about HackerOne. Then, I had a technical round where they hit me with questions about OWASP Top 10, different web app flaws, and how I understand triaging. The last round was a hands-on triage simulation where I had to show how I'd do a triage summary, assign a CVSS score, and manage cases in a test environment. It was all pretty clear and seemed designed to check out both my tech smarts and practical skills.
- How would you go about triaging actual vulnerability reports?
- What are your thoughts on the OWASP Top 10, and how do you apply that knowledge?
- Tell me about different kinds of web application vulnerabilities you're familiar with.
Software Engineer
So this company claims to be "remote-first", but then during the hiring process they told me they were looking to hire people who were based in London, even though the manager wasn't based there. This felt a bit off and like a waste of time because they could have just said that in the job description.
- Standard screening questions asked by talent acquisition.
