Very limited opportunities for upward mobility, upper management could careless about your work-life balance or your health, not even during a global pandemic. Extensive learning curve, depending on the vertical. You better meet your quota, or be at risk of termination, regardless of your tenure with the company. You'll learn about the other verticals but won't get the opportunity to cross-train or switch to a new product until after 2 years of employment. No equity either, so good luck in the long-term investment!
