Pros
I've been here under 3 years, and the size of the company has doubled. Twice. It's not a question of "Will there be opportunities for me to take on a new role?", but rather, "Which of the 3-6 interesting new roles available most interests me?" The benefits are great, and unlimited vacation is amazing (yes there are people who use it fully- taking a month or more at a time and still crushing their jobs), but the best part for me is the people. Yeah, the hiring process is selective, but totally worth it. Hiring managers do a fantastic job at finding intelligent, passionate people who consistently bring up the average. It would take something really drastic for me to consider leaving any time soon, but if the volume of Linkedin recruiting messages I've been getting is any indication, HubSpot will continue to do great things for me even then.
Cons
The entry level pay for services positions is not the best. I get that it's a case of supply and demand, but I hope that going forward we follow the example set by Google, Facebook and others to entice the very best applicants for every single position.
