Salary SUCKS! This is something I've heard from people across departments too! If you're looking for a job here, be prepared for them to lowball you with the salary unless you're going into Sales. Once you work here already, they'll try to promote you and give you way more responsibility with not much more pay.
They want you to think they're devoted to you as an employee and say one of their values is to, "Do the right thing, because it's good for business." But they don't pay staff what they are worth for their work. I've also seen a number of people get promoted into new positions and start taking on more responsibilities but not get a pay increase for as long as a month or more! This is mainly in customer success.
The explanation for this is that "HR is just too busy" or "HR takes time to pass these things through". But in the meantime the staff is expected to continue working a more demanding position without a corresponding pay increase. That sound like doing the right thing to you?
They'll try to lure you in with the cool atmosphere and "perks" like a pool table, and free snacks, but at the end of the day their compensation package is garbage and they regularly underpay. Also the company still isn't profitable yet, so if you're looking at the big picture then that's an issue that can't continue and doesn't look good for the company if they can't turn a profit.
There are a number of positions here that are dead end positions that don't really lead anywhere within the company and don't have a clear promotion path. Many customer success managers, some positions in value added services.
At the end of the day it's an okay place to work in terms of atmosphere and people, but don't stay for too long because the earning potential simply isn't worth it.
