Vantaggi
MongoDB has always been quick to pivot on sales strategies and genuinely seek honest feedback from sales team as to how things can improve. Resources are always made available if you can make a case for them. Compensation is above average.
Svantaggi
Product can be a difficult sale. The open source version is so rock solid and universally loved that it can be near-impossible to convince even the most avid users to pay for enterprise features. Constant back and forth between sales and engineering exec team on which features should be made free for greater adoption and which should move to enterprise to actually make money. Many members of management come from the same 1-2 companies so the culture is very similar to former companies and hiring tends to focus on former employees as well.
