I applied through other source. The process took 1 day. I interviewed at HubSpot in Feb 2025
Interview
The recruiter sent me a coding prompt to complete before speaking with me. The prompt was a 3 hour coding prompt that could be done in any programming language, upon completion, the would process to other inteviews.
Interview questions [1]
Question 1
They send you a prompt, You need to get data from and endpoint, transform it and send it back to another endpoint. The post on return will only return 200 if you have the exact answer.
It was to be done in a period of 3 hours which was definitely cutting it close. I was able to get the data and transform it, but because I did not have the exact correct answer, I could not post. I ran out of time writing tests.
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.
