If you work hard don't expect to get paid more. They require people to work for six months in a position with additional responsibility before they will increase your pay rate and formally promote you. They call this a "Star" position.
I'm not even sure if QuEST has a human resources department. Every once and a while they'll send out company wide emails about policy changes, but It's almost impossible to get a response from them when you have an HR related problem.
They will tell you during your interview that you will get a good amount of paid time off, but they don't tell you that it takes 3 years before you actually get that amount.
They will tell you during your interview that they have a 401k matching program, but they won't tell you that they only match 25% of the first 4% of your paycheck.
They will tell you during your interview that they pay for higher education, but they won't tell you that they pay $2,000 per semester per candidate (whichever is lesser) to up to five North American employees. There are hundreds of North American QuEST employees, so good luck.
They will tell you during your interview about the job that you applied for, but they don't tell you that there is a very good chance that you will be put on a completely different project when you're hired.
They will tell you during your interview that they have multiple health insurance plans to choose from, but they won't tell you that all the plans are garbage.
They will tell you during your interview that you will receive a yearly bonus, but they won't tell you that the bonus is largely based off company metrics so you should only expect about half of it. Also, no one knows what the company metrics are or what they are based off of. They just say every year that they didn't meet their goal, with no further explanation. If you try to ask for an explanation they will tell you that it's "confidential".
They will tell you during your interview that they have training courses, but they really don't. To be honest they have some kind of online training, but no one knows how to use it or sign up for courses and charging your time to overhead activities (like training) instead of charging the customer is a sin in the eyes of management.
As long as you want to work at QuEST knowing that you are only going to be there for a couple years to gain experience then I highly recommend it. If you want to be hired at QuEST because you want it to be a lifelong career, then I would advise to look elsewhere.
