I have found that Lewis Fowler is a management consulting practice that gets to know you as they are filling active positions. That does not mean you will get the first position that comes along - they have client needs to meet as well. My experience with LF is that they go the extra mile and find a fit that works for the customer and for the consultant.
Cons
Just remember that ANY consulting practice means that it is temporary. If you get a large project or dovetail well with the company that you consult with, the contract can extend. But any consultant knows that a contract can end early or be cancelled as well. I think this is a Con for being a consultant not in working for Lewis Fowler. LF has to manage to that practice.
