How to apply this 'auto post title' function to a specific post-type only

How would I apply this function to a specific post-type only, let’s say CPT XYZ?

add_action( 'save_post', 'wpse_214927_alter_title', 10, 2 );
function wpse_214927_alter_title ( $post_id, $post_object )
{
    // Remove the current action
    remove_action( current_filter(), __FUNCTION__ );

    $post_date      = $post_object->post_date;
    $format_date    = DateTime::createFromFormat( 'Y-m-d H:i:s', $post_date );
    $date_formatted = $format_date->format( 'Y-m-d' ); // Set correct to display here
    $post_author    = $post_object->post_author;
    $author_name    = get_the_author_meta( 'display_name', $post_author ); // Adjust as needed

    $my_post = [
        'ID' => $post_id,
        'post_title' => $author_name . ' Job ' . $date_formatted // Change as needed
    ];
    wp_update_post( $my_post );
}
