Everyone thinks the cons sections are written by disgruntled ex-employees, but in reality many of us are looking out for the next round of candidates because we know firsthand what it was like to work here.
The work life balance is non-existent and the culture is toxic. During my tenure, I had asked for one week of vacation almost 5 months in advance. I was told "it would be best it you don't take more than 2-3 days at a time, can you shorten your trip?", despite both my male counterparts taking 2 and 3 weeks simultaneously.
Unfortunately, when you have a young company, there is also a sense of entitlement and lack of work ethic. People expect promotions way too soon (as promised during the interview process) and when you have to put a team member on a PIP (which is a tool to help them) it comes across as a personal attack. I have coached teams in the past of all backgrounds, ages, education levels, etc and have never had more pushback from reps than in this organization. If they didn't like what you said, they would go over your head to your boss to complain. The kicker - they were being asked to make more calls (a core part of being in sales!).
Upper management is also a disaster. They promote individual contributors to management with zero training on the proper way to coach and support teams. Just because you are good at sales does not automatically make you a capable manager. Upper/middle management is even worse. Many still try to stay relevant and will go out drinking and share too many personal details with sales reps (sex life, drugs, etc). Its no wonder that there is no sense of respect or boundaries within the hierarchy.
The vision they paint for you is amazing and everyone drinks the Kool-Aid for their first few months, but once you are out and look back on that period of your life you realize that it was one of the most toxic experiences you could have been a part of. Believe these stories and listen to your intuition as you consider your next role.
