requiredCertifications, and then to compare the sizes. Equality means that
User meets all requirements.
rule "meets requirements"
dialect "mvel"

Position( $certifications: requiredCertifications )
User( $name: name, $profile: profile )
$got: List() from collect ( AcquiredCertification( certification
memberOf $certifications ) from $profile.userCertifications )
eval($certifications.size == $got.size )
then
System.out.println( "Hire " + $name );
end
