I applied through a recruiter. The process took 1 day. I interviewed at HackerOne (London, England) in Sep 2025
Interview
The company advertises itself as “remote-first,” but during the hiring process I was told they were prioritizing candidates based in London, even though the hiring manager wasn’t London-based. This inconsistency made the experience feel misleading and wasted time that could have been avoided if the job description had clearly stated location requirements.

Question 1
Normal screening questions with talent acquisition
I applied online. The process took 3 weeks. I interviewed at HackerOne (Pune) in Aug 2025
Interview
The interview process began with an initial screening by the recruiter, followed by a hiring manager round that focused on my background and behavioral questions to assess cultural fit. Next came a technical assessment on HackerRank, which tested my understanding of Ruby on Rails. After that, I had a live pair programming session - a very engaging and challenging experience. The final technical stage was a system design interview centered on real-world problems, before concluding with a pre-offer discussion.
Throughout the process, everyone I interacted with was highly professional, supportive, and accommodating. They took the time to understand my background, provided timely feedback, and scheduled interviews based on my availability. A special highlight goes to the recruiter, who kept me consistently updated and ensured smooth communication at every stage.

Question 1
Can you explain a challenging and interesting problem you solved in your previous projects? What approach did you take, and what did you learn from it?
I was contacted by a recruiter on LinkedIn. Went through a standardized process of speaking with a recruiter, director of engineering, and down that path. My schedule was limited and that caused me to miss the opportunity with a team but the conversations where matching so well that they provided another team to join.
Hannah my recruiter was great. She kept in constant contact and helped hold expectations. She provided confidence that HackerOne was worth my time and energy in the conversations.
