Pros
Work life balance does exist to some extent. If you're lucky, you'll get on a project that is right up your alley. Not much travel mostly local.
Cons
Benefits are the worst of any company or consultancy I have ever worked at. Salaries are competitive in the middle. They need to consider stronger salaries if the billing rates are rising and they can claim business is growing. Reward the people laying the foundation. The org chart is very flat. The opportunities for promotions or to show ANY future employer that you had career growth here will be difficult. Many in sr. mgmt. are recruited from outside, and are highly experienced but moderately talented. These are mostly individuals with lots of experience, but left their previous employers because they could not succeed any further. Slalom doesn't land any 'name' executives or managers from rivals that are truly on their way up. Do not expect to be given a clear indication of where you stand or where you're going within the company. Operations here is similar to pulling strands of spaghetti apart with a chop stick. This place, at it's heart, is staff augmentation, with the consulting company tagline added in. Don't believe the hype that it is one of the best places to work because some organization said so. Slalom markets that to death.
