This is where careers go to die
Pros: It is a big name on your resume, assuming you do two years maximum and leave
Cons: Absolutely no mobility whatsoever.   Top 1% performance and a glowing review will net you a salary increase which barely keeps pace with inflation.   Promotions do not happen within your line of business, however you are not eligible for cross platform increases either.   The firms stated solution to this is that you should basically hop from department to department, remaining at each for 2-3 years and maybe after three or four cycles of this your direct supervisor will get hit by a bus and you will be one of 20 people considered for promotion.  Even if this occurs, the firm has a history of increasing your title, giving you more direct reports and then later cutting the position before you ever see a pay or title increase.   

TL:DR,
As a clear top 1% performer, I can confidently say that death or retirement of a direct supervisor is your only chance at advancement.   Avoid this trash heap like the plague.
