One way to find out more about a company, the 'real' down and dirty, is to scout out some employees or owner-operators, and get some info from them. When you're talking face to face with someone and can ask direct, specific questions, for the most part, you'll get truthful answers.
Recruiters have a job to do. Sometimes they don't mean any harm, but they often are not very accurate when answering questions for hiring. The recruiters work for the carrier, and their job is to get more drivers/owner-operators on board. Some will deliberately mislead the applicant, just to get them on-board. Ask as many questions as you're able, and then verify the answers with a presently employed o/o or company driver. Also, try to find out if there are folks who have been with the company for a long time. This can be a good indication that there may be a future in driving for this company. They must be doing 'something right', to keep people for long periods of time. Just a few ideas, that may help.
