Pros
Slalom is a great company to work for. The culture within the company is diverse, yet it works. Because of the diverse group of people that work within the organization, there is a match for every type of customer. The local-resource model is excellent. Being able to work in the community where you live, and work with customers just outside your door is a welcome change to the typical consulting model where consultants spend numerous hours traveling to and from customers - coast to coast - which eat into family time. Heading out to the customer, and being home for dinner is the best of both worlds when you enjoy consulting. Furthering your education and expertise is only limited to your ability to manage your own time.
Cons
You need to understand and feel comfortable with consulting. You will start a "new" job every few moths in some cases. If you are comfortable with the consulting model, Slalom has very few downsides to their model.
