I have added the following code to job-pagination.php, but still the pagination links is redirecting me to same page

<?php
/**
* Pagination - Show numbered pagination for catalog pages.
*/
if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly
if ( $max_num_pages <= 1 ) {
return;
}
?>
<nav class="job-manager-pagination">
<?php
echo paginate_links( apply_filters( 'job_manager_pagination_args', array(
'base' => esc_url_raw( str_replace( 999999999, '%#%', get_pagenum_link( 999999999, false ) ) ),
'format' => '',
'format' => '',
'current' => max( 1, get_query_var('paged') ),
'total' => $max_num_pages,
'prev_text' => '←',
'next_text' => '→',
'type' => 'list',
'end_size' => 3,
'mid_size' => 3
) ) );
?>
</nav>
