The short version:
1.) Horrible, unqualified management, 2.) low pay, extreme hours and high demand, 3.) zero support and poor communication.
The long version:
Management, particularly on the sales side of the organization, is a major failure. Starting from the top down, the initiative for the past couple years has been to bring in people from the fashion or "high end retail" industries who have ZERO knowledge of the product, the company culture, the automotive industry, and no desire to actually learn about it. These people are given management positions without proper training or education, and lack even minimal base knowledge to do their jobs well so instead they rely on statistics/metrics in hopes that they can succeed by playing a numbers game. They do not have good intentions for the company or it's long-term success, and have completely destroyed what was once a great culture and environment to be a part of. People who have worked for the company for years and dedicated themselves to the mission aren't given any consideration, and very few promotions from within ever occur anymore. There is rampant sexism and favoritism at almost every level, if you have any aspirations to advance in your career, it won't happen here.
The pay is awful, you will be expected to work a minimum of 60-70 hours a week, available 7 days a week, for a 40hr/week salary. Commission for sales is insulting (approximately one-thousandth of a percent of the cost of the vehicle), you don't get paid until the car is delivered (which, as a member of the sales team, you have ZERO control over and can take 8+ weeks in some cases), and you get to work in an environment where your employment is constantly being threatened by your boss(es).
HR doesn't do anything to correct any issues brought to their attention, they do not look out for the interest of the employees in any way, shape, or form. Emails and phone calls to just about any department often go ignored on a consistent basis, and regardless of how valid it may be, no one at any level of management wants to hear about the problems that exist and how to fix them. If you speak up, you will most certainly have a target on your back and I guarantee you will be subject to retaliation at some point or another. It is abundantly clear that the employees who are down in the trenches, bending over backwards to try and achieve targets and satisfy customers are thought of as completely expendable. Meanwhile, those who act with no regard for ethical behavior and professional courtesy are often the ones to benefit from promotions, it is truly disturbing.
