Average work place with no growth - Consultant Capgemini Employee Review

No Growth. After 5 and a half years i am almost at the same level as any fresher will join today. Not because of my performance but because of no knowledge to the Senior managers that why the rating was brought down or why the desired or eligible promotion was not provided. When you ask your manager or the Senior manager why the expected rating was not the final rating or why the promotion was not give the reason given is that they do not know. This is not once i have been given the reason regularly for 4 years i have heard positive comments with low rating.
