    In other jobs I wasn't motivated to get up everyday and go to work. Yes compensation previously was nice but there was no substance. GMS provides a positive environment conducive to wanting to go to work to succeed and enjoy the company of great coworkers. Plus the money is fantastic.


    Absolutely none. Shoot, you get a company car. How could that be bad?

    I applied through an employee referral – interviewed at Group Management Services.


    The interview process took about 5 weeks. Very thorough. Initial interview was via webcam and just an opener. It was followed by an interview with the local branch manager, hiring specialist and then VP of Sales. Also shadowed a salesmen for a half day and got some very good insight on the company and what they do. Overall it was a very good experience and a good company. Employees seem very happy.
