Vault Verdict

As a firm specializing in advice on all things HR—from investment and retirements to “workforce rewards”—it’s no surprise to find that Mercer’s employees are, once again, delighted with life at the firm.

Employee Reviews

  • “A blend of economics and empathy. We want to make money and we know that people are key to doing that. Meeting people where they are is great for clients and colleagues.”
  • “Know that you will work with the smartest and hardest working people and learn so much very quickly. Also know that you will work very long hours and it will be hard work. You must be very organized and willing to put in the work in order to succeed.”
  • “Mercer's culture is absolutely a cut above all other consulting firms. The highest caliber consultants and subject matter experts work well together and help one another do right by our clients. No other firm is as collaborative and committed to shared success.”
  • “Try to really understand who you will be working with on a day-to-day basis (immediate manager, project team, colleagues). Is it a collaborative environment or a competitive environment? If it's the latter, make sure that is the type of environment you want to be in.”
  • “You have to be willing to work hard, be motivated to make a difference for clients, be supportive of colleagues and be willing to step outside your comfort zone.  The work will have peaks and valley of intensity but the learning and development you will get at any level of the organization will pay off significantly.”

Getting Hired Here

  • “Actively trying to recruit more experienced hires as well as college recruiting and internship program.”
  • “I think we are looking for diversity in our candidates that have high analytical skills, great client ready communication skills - written and oral, are highly collaborative and able to work in a team environment, able to deal with tight timelines and changing demands, and experience in our industry. “
  • “Recruiters are good about closing the loop with all candidates. Ideal candidate depends on the line of business, hiring manager, etc. But we are always looking for a good cultural fit.”
  • “The interview process actually involved an excel quiz, which was great to see rather than just behavioral questions.”
  • “The interview process involved conversations with the hiring manager and that was really it. It was nice, simple, and completely relaxed. One of the best interview processes I've been through.”
