Hi Max,

You can simply alter the Label using erp_recruitment_minimum_experience filter. Use this snippet below and change the label as needed. You can change other labels as wel,l you can look into wp-content/plugins/erp-recruitment/includes/functions-recruitment.php line 50. for more details

function rt_change_min_exp_label( $min_exp ) {
    $min_exp['Fresher'] =  __( 'Too Fresher', 'wp-erp-rec' );
    return $min_exp;
}
add_filter( 'erp_recruitment_minimum_experience', 'rt_change_min_exp_label' );

Let us know if you have any other queries.

Thanks
