Vantaggi
People are very nice, willing to support and teach you. Great mentorship opportunities if you seek them. Seniors on projects give lots of leeway and trust to PMs and associates to prove themselves. Projects can be hit or miss, but I got lucky with mostly interesting companies/products. Multiple staffing model gives exposure to more projects in a shorter period of time. If you stick around and are good, early promotions are attainable (although you are ineligible within the first year of hiring despite performance). Vacation policy is technically unlimited, but finding time to actually take time off is very challenging unless you plan months in advance. Excellent exit options into industry.
Svantaggi
Highly exploitative work environment where new hires are fresh meat to overstaff across multiple projects. Staffing model routinely spreads junior consultants across 3-4 projects even though it claims 1-2 projects, setting junior consultants up for long hours and unmet responsibilities. Bonuses are laughable and recognition is lip service only.
