Overall the process took 1.5 months. I had a call with a recruiter. The usual screening call. She came back to me quickly and moved me to the next one with the Hiring manager for the position. That happened 2 weeks later. We had a nice conversation digging into how I build projects, how I define strategy, product discovery, etc. I got immediate feedback from the recruiter on the next day that I'd be moving to their final round of interviews. That for some reason took 2 weeks to schedule and finally happened 4 weeks after the second interview. It took 3.5 hours, 4 separate sessions with the hiring manager and 3 other people. All of them were nice people, some of them more experienced than others, but generally was left with a good impression of the people in Hubspot. I also thought the interviews went well but I wasn't offered the job at the end. At least they provided me with some reasoning for not making the offer which I appreciated. It would have been nicer to call me in person rather than send an email at 5.30 in the morning (the recruiter was in Ireland) when the rejection was the first thing to see at the dawn of the day. All in all, the people were nice, the product seemed nice too and I was left with the impression Hubspot is a nice company to spend time in. The recruitment process was way to heavy, not only because of the time it took me (the recruiter apologized at some point that it doesn't usually take that long) but they were sending me materials to go over and prepare for the upcoming interviews which were out of line totally. They send me a list of topics and questions for each topic in that long session interview to prepare for them. Well, I did prepare and I don't consider it a waste of my time but none of these particular questions/topics were ever raised.
