Ranking and Rating Methodology Respondents to the Vault.com survey rated accounting firms on these seven dimensions or attributes (the percentage weights in parentheses are applied to derive the overall ranking): Prestige (40%)Firm culture (20%)Work-life balance (10%)Compensation (10%)Overall job satisfaction (10%)Business outlook (5%)Formal training programs (5%) Additional Criteria Though they do not factor into the overall ratings, Vault.com also includes these evaluation criteria in its surveys: BenefitsClient interactionGreen initiativesFirm leadershipHiring processHoursInformal trainingInternal mobilityPhilanthropyPromotion policyRelations with supervisorsTravel requirements Also measured is diversity along each of these dimensions: OverallFor womenFor minoritiesLGBTFor people with disabilitiesFor military veterans Limitations of the Rankings While the rating and ranking methodology used by Vault.com is highly detailed, it nonetheless represents a summary of the personal opinions of survey respondents. As a result, it is fundamentally highly subjective. Accordingly, these rankings may or may not be representative of your own preferences in choosing among employers, work situations, and career paths. Another open question is how closely the pool of survey respondents actually represents the opinions of all employees. Although the Big Four fill the top three spots, they regularly score much lower (usually in 20th place or below) along the dimensions that are most indicative of their desirability as places to work, most notably firm culture, work-life balance, and job satisfaction. Being the top four in prestige, which gets the highest weight, accounts for their high placement overall. It suggests that the Big Four may be more desirable as resume-building stopovers in a career path pointed elsewhere than as long-term career destinations. In the 2013 survey, BDO ranked 29th overall. By the next year, it entered into the top 10, where it has remained since. Such a dramatic move raises questions about the robustness and quality of the survey samples.
