With aboslutely no idea what your database structure looks like, I'll have to guess....but a GROUP and COUNT will work.

SQL

SELECT
     Year(EmployeeStartDate) AS YearHired, COUNT(EmployeeId) AS EmployeeHiredCount
FROM
    EmployeeDetails
GROUP BY
    Year(EmployeeStartDate)
ORDER BY 
    Count(EmployeeID) DESC

Assuming you've got a table with Employee details and always record their start date, you can use the YEAR function to group and count by that field. See if you can figure out how to select the record you're interested in.
