Pros
I have been at HubSpot for a long time and at this point in time, there is probably a 25% chance you have a Tech Lead who takes ownership for their role and team and is invested in the development and coaching of their individual contributors. If you get one of these tech leads, you can feel confident you will be in good hands and receive actionable and valuable feedback. There are strong mentors and empathetic people at HubSpot, but in 2023 those in management roles are rare. If you're on a good team with a good TL, it's possible you won't know how bad it is on other teams.
Cons
Tech leads have no ownership or responsibility for their team. Problems that occur are treated as the fault of individual contributors and not the tech lead responsible for training them. Tech leads do not know how to be invested in the growth of their engineers. I wish I could share some of the feedback and reasons for termination I've seen peers be given. People are being humiliated in public slack channels and their feedback/reasons for termination are lists of pedantic communication points with no proof the tech lead ever tried to coach or help them. These tech leads are often strong engineers who were put in the tech lead role out of necessity and treat the role as a boosting of their own ego. Many lack empathy, patience, and grit to be a people manager or coach. There should be a reason these roles are paid what they are, but many of these TLs are failing in their role. I do many interviews and have long been a promoter of HubSpot. I have been grateful for how HubSpot has helped me grow myself. But what I have seen in public channels and behind the scenes to colleagues shows that this is not an environment in which people will be invested in. Your growth is not important here - only for other engineers to inflate their own egos. I've become embarrassed to work here, and I think it's not long before this is the reputation of HubSpot as a whole in the tech sphere.
