This is from experience and includes facts, not just a bias opinion.
They may tell you that you are an employee and not a contractor. This is a false sense of security meant to keep you operating at your full potential until the end of a contract and consequently unemployment. They will also tell you there is a contract coming soon in order to keep you on standby in the off chance they are awarded a contract, therefore, can put you in place immediately and start charging the client. This consequently keeps unknowing persons from finding other employment. I was lucky enough to not fall into this category, but I know people who have.
They also severely underpay their employees, therefore, hire entry level persons willing to work for less. There are employees in management positions with no more than a three month certificate course in GIS. On one occasion, I was cussed out over the phone by a "management" person blaming me for a mistake she made.
Employees who leave the company generally have nothing but positive things to say about the company. Anonymously, however, reviews clearly show this is NOT a company you want to work for. Know the difference between reviews of employees looking for a good company reference and those who are speaking truthfully.
