About your past

Tell me about an open enrollment you helped plan. What went wrong, and what did you change the next year?

What they are checking: Real experience running enrollment and learning from the problems that always come up.

How do you work with a benefits broker so that you get real advice and not just their preferred products?

Tell me about a time you collected employee feedback on benefits and it actually changed a program.

What they are checking: Whether they close the loop on feedback, which the posting asks for directly.

What would you do

An employee calls upset because a claim was denied and they think the plan should have covered it. How do you handle it?

A manager asks you about a specific employee's medical leave and benefits use. What do you tell them?

You're juggling a system enhancement project, a vendor issue and open enrollment prep in the same month. How do you set priorities?

What they are checking: Ability to manage multiple deadlines without letting accuracy slip.

About the work

Walk me through how you ran an RFP to select a benefits vendor. How did you build the scoring, and who had a say?

What they are checking: Whether they can run a fair, documented vendor selection that holds up to review at a federal contractor.

How do you use utilization data to decide whether a benefit program needs to change?

What they are checking: Whether they turn claims and usage trends into specific recommendations rather than just reports.

Which compliance rules do you track most closely in benefits work, like ERISA, ACA reporting, COBRA or HIPAA, and how do you stay current?

What they are checking: Working knowledge of the laws that create real penalties if benefits are run wrong.
