I applied through a recruiter. The process took 1 week. I interviewed at HubSpot (Cambridge, MA) in Aug 2014
Interview
The recruiter sent me a message on LinkedIn in May 2014. I didn't reply until I was looking for a job, which happened in August same yer. He replied fast and arranged a phone conversation on the next day.
I talked to the recruiter on the phone once and he arranged an online test. I took the test on the same day.
Two days after that he called me and scheduled an in person interview. I came to Cambridge and I was interviewed by a tech lead, a software engineer and a director. Each asked different questions and explored different aspects of my skill set. The tech lead explored algorithms. The software engineer asked me about data modeling and performance optimizations. The director asked about previous jobs and I showed him one application I've built. After that we talked about the data model and architecture of my solution and future steps for it.
Interview questions [1]
Question 1
One of the questions that was asked was:
Given two sorted lists (or arrays) and a number k, create an algorithm to fetch the least k numbers of the two lists.
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.
