The main stages were a coding challenge, a behavioural interview and finally a long interview with two senior level engineers.
The entire process went very smoothly and was one of the best interview experiences I've had to date.
The coding challenge was a very interesting problem that allows you to code in your chosen development environment in whatever language you choose. Definitely practice your HTTP libraries and common data structures such as sets, hashmaps and arrays/lists.
The behavioural part was more of a friendly chat and open ended discussion on your experiences and why you applied to the position.
Finally the last stage interview involved a high level systems design / database problem and standard coding problem with edge cases. These were followed by questions to do with your experience as a developer. (Work experience, open source contributions, personal projects).

Other Software Engineer(Internship) interview reviews for HubSpot
I applied online. The process took 2 weeks. I interviewed at HubSpot (Boston, MA) in Oct 2025
Interview
The interview process was two hours long. One hour JavaScript technical and one hour coding technical. Overall, chill interviewers and the questions were fair game. I would go through other posts on glassdoor.
Interview questions [1]
Question 1
JSON related question and basic JavaScript questions
I had one of the best interviewing experiences. it started with an OA involving API calls, followed by a thoughtful behavioral round, a LeetCode-style coding challenge, and a system design interview. The recruiter was incredibly kind and communicative throughout, and all the interviewers were chill, and helpful.
The interview process was really quick. A coding problem gets sent to you, then recruiter interview and last round is 2 1 hour meetings with an engineer. One was system design and other was leetcode easy/medium
