The Sales organization is extremely toxic. Indeed's HR communication is all about diversity and inclusion, but the sales organization is extremely fraternal. It is mostly white men in their 20s in Inside Sales. If you want to grow anywhere in the Sales Org, it is fully determined by your willingness to suck up to the Senior Director.
It is very, very, stressful and the goals are almost always unrealistic with most of the org missing their targets.
Upper management does not hire good PEOPLE managers, they hire based on who was able to work their book the best way which is often time based around luck. The new managers lack interpersonal management skills.
