The Vault Guide to the Top 50 Banking Employers rates more than 85 investment banking firms with significant operations in North America. Vault chose these firms based on previous Vault surveys that gauged opinions of industry insiders, as well as on various factual data, including annual revenues and number of employees.
Vault asked these firms to distribute the Vault Banking Survey to their investment banking professionals. The Vault Banking Survey consisted of questions about life at the professionals' firm or former firm, along with a prestige rating.
Survey participants were asked to rate and comment on their firm's hiring process, culture, compensation, diversity, training, green practices, business outlook, and more. Participants were also asked to rate companies other than their own in terms of prestige on a scale of 1 to 10, with 10 being the most prestigious.
