How do I find next greater date in excel?

I have a sheet with three columns:

[Employee ID] (Distinct values)
[Start Date]
[Stop Date]

I need to search a second sheet with two columns:
[Employee ID] (Non-Distinct)
[Testing date]
and return the next greater [Testing date] than each [Stop Date] on the first sheet for each employee.

I am using latest Excel 365
