Pros
Browserstack is among the best SaaS companies and I think it would represent top 5% talent, pay, culture. After working at this company you will get really good offers from other companies. Unlimited PTO (But this really depends on Manager's mood whether they approve) Competitive Pay Market leader in the software testing space. Overall would rate an 8.5/10 - They're not perfect, but they do a lot of things right.
Cons
Some sales teams are at a big disadvantage - Quotas are the same but some geographies are very tough to operate in Some managers can make your life hell to work with. Constant pressure and unnecessary demands for the smallest things. There are some really good ones too, so your experience would depend on luck. Pretty difficult for you to grow fast in your career. You would need to do exceptionally well, and be in really good books of your manager to get promoted. Otherwise it takes years to get promoted. Poor Pay transparency - They will give you good hike only if you have another offer.
