I applied online. The process took 2 months. I interviewed at HubSpot (Dublin, Dublin) in Jul 2024
Interview
The system design interview lasted 60 minutes, with the first few minutes dedicated to introductions and clarifications, followed by a deep dive into designing a scalable system. The interview was highly interactive, with the interviewer asking follow-up questions to gauge my thought process.
