The outlook at Mckinsey is usually quite negative for business analysts. Growth is only possible if you have a MBA under your belt. Usually people are willing to accept other offers when they are giving.

Growth within the company is mandatory. You will not find people staying in one position for more than 3 years. This doesn't suite me that well because I prefer to move up within a company when I feel that I am ready. It is stressful because you constantly feel that you have to move up or you'll be out.

The growth in the company is up or out. If you prove that you can bring great things to the company and create great value, then you will immediately be rewarded for your hard work. If you do not perform well, or are just mediocre, then the company has no need for you and you will be removed from the company. This is good for me because I want to work with people who care about the company and that are able to bring value.

The growth in McKinsey is up or out. You will be rewarded for the value that you create and your ability to perform well with the clients. If you underperform or just perform at par, you will be booted out of the company. The growth is good, but at times it feels like you get moved up when you had just gotten comfortable in a position.
