Pros
You can't help but gain a lot of experience because you'll be working a lot of hours. Equity Methods also has good professional training; they are striving to offer a 'white-glove' service, and they certainly achieve that. Challenging, interesting, and niche work. A lot of the work is building reports using SAS. They don't require you to know how to code before starting and they will train you.
Cons
Very long hours, especially for the compensation: I worked an average of 65 hours per week. It doesn't get better as you progress through the company: senior consultants are also working long and stressful hours and are poorly compensated for the industry. Attrition is very high. They hire a lot of people every year. 25%-50% of new hires are fired within 3 months, and after 2 years only 1 or 2 remain.
