Pros
In hindsight nothing at all
Cons
They force distribution, you may be a great performer but if you aren't one of their favorites then the "bar is always shifting". Upper management who likes to refer themselves as leadership is extremely incompetent, they will throw you under the bus for their mistakes, not to mention they have their favorites, I remember having a PA in our org who was applauded & promoted for creating a reusable one stream consumer, which is an out of the box functionality. Upper management will almost certainly target the new hire because they were hired with the intension to fire i.e. to meet the quota of below-strong 12%-15%. 360-reviews & feedbacks are totally meaningless, and are totally skewed & twisted during reviews and do not reflect the truth. I worked with my manager for more than a year and delivered on a major transformation project, but just before the year end performance cycle I was asked to report to a peer (Red Flag). My previous manager did not endorse the good work that I had done and I was let go to meet the quota.
