It's not all roses. We have had some turn over of long-term people in the past year (2016), and last summer was particularly turbulent. There were some white knuckle moments for all employees and some of our customers felt the effects as well. But we've hired in great talent, are changing our process and moving our platform forward to a robust, scalable one.
There are some "sour apples", as there are in every company, and you do need to stay pretty connected via Skype or HipChat to your peers so that you are aware of the dynamic nature of this nimble company.
We tend to go through cycles with high visibility from executive team on the direction of the company to lower visibility periods (maintenance cycles, I call them). Depending on where you are, this can seem frustrating, but it's a normal cycle of things. I think high-strung people may have a harder time than laid back types.
The company is VERY metric based. Decisions from the top are made this way, and your actions are (should be) very based in metrics - what's going to have the biggest impact, how much cost benefit do the hours you spend on a task, etc have - that sort of thing. That said, there is a ton of help for you to succeed at QLess. Mistakes are learning opportunities (unless you can't learn from them), and there is a wealth of experience to help.
