I applied online. The process took 1 week. I interviewed at HubSpot (Cambridge, MA) in Mar 2016
Interview
They give you a brief tour of the office. The buildings are great, awesome perks. After that I had three, 45 minute interviews. There is more talking than actual coding if you carry the conversation. The first two interviews, you interviewed with one person, last one was with two people. Everyone was really nice but the guy in my second interview didn't seem like he wanted to be at work that day, kinda grumpy and over critical I thought. After the three interviews you meet with your recruiter quickly and you're done. They said they make a decision in a day but it took several for them to get back to me. Same thing happened to a friend of mine, waited for a while too.
Interview questions [1]
Question 1
First guy had me do simple stuff in jQuery that resembled a basic Twitter app. If you can create a simple Twitter clone in just jQuery you'll be set. Second guy asked me to build a simple function that could be done using a while loop then cover the edge cases. Last guys you built more simple functions like given a string, add a comma between each letter except the last. Know how to add things to the prototype.
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.
