It's your typical sales job - grind it out chasing the carrot on the stick. If you do manage to make a sale, despite never being trained on what you are selling, there is a good chance that it will either fall apart during installation, or it will get deployed wrong - so kiss your commission goodbye. Once you actually make commission, there is a good chance that the company will restructure your attainment plan, so they can pay you less the next year.
If you stick it out through all that, you will be rewarded with a severance paycheck when they lay you off... I myself was laid off twice, though the first time was a clerical error they overlooked; I was only paid for the second layoff though. GOOD LUCK!
