Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

MercerWell works on employee health, from prevention to complex clinical management. What draws you to employer-based population health rather than a provider or payer setting?

What they are checking: Whether they understand that the employer is the client and that health strategy is tied to business cost and engagement.

Tell me about a time you analyzed survey data. What did you find, and how did you present it?

What they are checking: Comfort with survey data and turning it into a clear message, a named part of the MercerWell work.

Describe a time you had to influence people to change a behavior or adopt something new.

What they are checking: Insight into change management and engagement, which the practice names as part of its work.

What part of your master's program prepared you best for consulting work, and what gap are you hoping to close this summer?

What they are checking: Self-awareness about strengths and learning goals for a short, intensive summer role.

What would you do

A vendor's proposal promises a large return on investment. A senior consultant asks for your view. What would you look for?

What they are checking: Healthy skepticism and the ability to test assumptions behind health vendor savings claims.

You are working on two client projects with different senior consultants and both want a draft on Friday. How do you handle it?

What they are checking: Proactive communication about workload in a team-based consulting setting.

About the work

You are helping with a wellbeing benchmarking project. What would you compare across employers, and what would make a comparison misleading?

What they are checking: Awareness that differences in workforce demographics and plan design can make raw benchmarks unfair.

Walk me through how you would help run an RFP to choose a health vendor, such as a diabetes or mental health program.

What they are checking: Understanding of structured vendor selection, including criteria, scoring, pricing and performance guarantees.

How would you judge whether a population health program actually reduced costs or improved outcomes?

What they are checking: Whether they think about baselines, selection bias and realistic measures rather than accepting vendor claims.

What do you see as the biggest health cost drivers for large employers right now, and how could an employer respond?

What they are checking: Current knowledge of trends like specialty drugs, chronic disease and behavioral health, and practical levers.

How would you explain stop-loss insurance to someone who has never heard of self-funded health plans?

What they are checking: Basic grasp of self-funding and stop-loss, which connects to the Stop Loss Clinical Oversight product.
