Pros
Good place to learn QTC, especially if you're new to consulting. Overall it's a good consulting company to start your career at. The employees are all friendly, and the culture is collaborative.
Cons
Not the right fit for experienced hires. Most leadership positions are based out of middle of no where Missoula, Montana. Experienced hires are treated like workhorses and their experience is not properly utilized. Leadership at ATG is pretty inexperienced, and most of the consultants at ATG have 1-2 years of experience. This is no where near the years of experience that are marketed by ATG. So, if you're an experienced hire there is not much room for career growth - since technical growth can be attained at any consulting firm. Be ready to teach your team members and hold their hands.
