Prepare to work. Work on weekends (and that's in the office on weekends). Work late in the evening. Forecast calls on Sunday at 4:00 pm before the Superbowl? Yep.
Management has a tendency to scream when things go sideways. I have personally witnessed a fair amount of tears being shed and public humiliation of employees when sales cycles or partner relationships do not proceed at the pace and schedule management expects.
You will not get an opportunity for any equity, which is reserved for the Chairmen, CEO, and Executive Management. "Equity is earned" is a common refrain told during the interview process. Then when you are successful, equity is to be discussed later during some future "moment of liquidity" when the company goes public or is sold. To be fair, the company's management treated senior and valuable people well during their previous market exit during the AirWatch sale to VMWare.
Sales is expected to generate all their own leads, there is no BDR / SDR / lead generation program. Marketing spends a lot of money doing tradeshows and just expects those leads to convert. Not a lot of thought is put into marketing programs and lead generation in general.
