I interviewed at HubSpot (Cambridge, MA) in Feb 2025
Interview
It's a 3 step process - phone screening with take home assignment - fetching data from API endpoints, processing it data structure and post the output. This was with 3 hours time limit. Next was a tech + behavioral screening - nothing much standard scenario based questions mapped with past experiences. Final was coding round (2 one hour sessions) focusing on medium to hard LC questions and then a FE JS around memoization, and closures. I had practiced on hackerrank, codewars and LC ofcourse. For mocks - I found a really good Hubspot coach on Prepfully who helped me uncover how to articulate thoughts on behavioral and was generally quite helpful.
I applied through university. I interviewed at HubSpot (London, England)
Interview
I went through several rounds, including an initial screening, a technical assessment, and follow-up interviews. The process was well structured, but I found the technical part challenging because it required both problem-solving and clear communication under time pressure. The interviewers were professional, and the questions were relevant to the role. Although I did not receive an offer, the experience was still valuable and helped me understand the company’s expectations better.
Coding assessment with multiple levels. levels open up as you pass them. Time constraints looked tight. I could not get through all levels. It was related to Designing banking system.
I applied through an employee referral. I interviewed at HubSpot (Dublin, Dublin)
Interview
Consists of an Online Assessment, followed by 3 rounds (2 System Design, 1 coding)
One of the System Design interviewer was less experienced (with an experienced shadow interviewer). I feel like they didn't drive it correctly, didn't ask me the right follow-up questions and eventually gave negative feedback.
