Vantaggi
Generally speaking, Booz is still the premier government contracting firm. The firm has a lot of highly talented and motivated people, and they do a wide variety of work for a wide variety of clients. Compensation is mostly competitive, and there is marginally more stability working for Booz than other firms.
Svantaggi
Corporate culture has changed dramatically in the past five years, and by all indications the firm is repositioning itself to be a data sciences firm, NOT a consulting company. If you truly want to be a consultant, you should look somewhere else, because the firm is not focused on its traditional management consulting. Changes to corporate structure have all been targeted towards improving the bottom line, and employee development and the opportunities to do different types of work for different types of clients have decreased dramatically. Changes have also put significantly more burden on the employee to manage their own careers, with no clear advocates or mentors, and very little way to find or connect to opportunities.
