The People Team Senior Leadership. I have never worked in an environment where the leadership is deliberately toxic. You can expect their leadership style to be hands off and brazenly political. They will hand you the reigns with high expectations, zero direction, context and then claim they informed you on everything. They will pose as a mentor until you make a mistake (which you most likely will since you have little to no direction,). You should also be prepared to take the fall if your people leader makes a mistake because they struggle to take responsibility. They will likely betray team members as soon as their egos are at risk.
With all that said, Pluralsight can be a great place to work so long as you are not under the current People Team leadership. Which is a shame since they have such so much influence.
