I applied through college or university. The process took 1 week. I interviewed at HubSpot (Cambridge, MA) in Oct 2014
Interview
Hubspot contacted me ~3 weeks after I met a recruiter at a career fair. They warned me the process took only a week and so I should decide when to start the interview process such that I could respond in that period of time.
First, there was a coding challenge: 2 problems, one was easy and the other appeared to be easy but I only got 1/6 of the tests to pass. Nonetheless, they called me in to give me a tour of the workplace and asked me about some projects I had worked on. Then, they asked if I was in a position to accept the offer. I asked for another 2 weeks of delay (I had other interviews) and then accepted the offer.

Question 1
Given an array of strings with only lowercase letters, create a function that returns an array of those same strings, but each string has its letters rearranged such that it becomes a palindrome (if possible, if not, return -1).
I applied through college or 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.
