I applied through university. I interviewed at HubSpot
Interview
The interviewer would talk with you through the phone in the first phase and then she will set you up for a interview question online. Hubspot will send the question to your email. The question is related to API (GET and POST).
Interview questions [1]
Question 1
Use the API key to access their API and process the data. Given a JSON-formatted data, format the data and return the result to another API. If the result is correct, then you will get a 201 code as a success.
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.

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
