The process took 2 weeks. I interviewed at HubSpot
Interview
Initially had a phone call with recruiter who was really helpful in every step of the way during the entire process. Then I was asked to solve 3 hour coding challenge related to ReSt service and JSON data processing. This exercise was easy but time consuming. After successfully completing it I had an on-site scheduled with manager and another senior IC. An interview with manager was more on the behavioral side. The technical interview question was very easy array leetcode question
and I solved it completely. Throughout the technical interview the interviewer seems to be confused with the approach and kept nudging me in other direction. Due to which I lost lots of time. She was poker faced whenever I asked any clarifying question and kept counter questioning me. For example the input to the question was not stated with her problem statement. When I asked her can I choose it to be list she said choose whatever you want. After choosing List input I stated my solution accordingly and then she asked me to have array as an input. I have heard so many good things about Hubspot interview process and I did not expected this. Maybe there are always some bad eggs in the basket. I was unlucky to encounter one. So despite solving coding challenge and tech interview question I got rejected. It was a waste of 5 hours. This may be just my experience but wanted to share here with community. Also I don’t know why but Hubspot pays what too less for senior engineer level. Also their stock sharing is peanuts.

Interview
Single exam no human interaction. The exam was like a college test, something completely unrelated to modern field work. Seemed a bit off base. Definitely didnt seem like a realistic approach to finding real humans to fit for a company.
