wp_insert_post custom taxonomy multiple Category not added

I have a custom post type jobs and a custom taxonomy jobCategory. wp_insert_post() and it works. When a user selects multiple jobCategory, only one selected category is recorded in the database. please guide me

if (isset($_POST['send'])) {
    $post_id = wp_insert_post(array(
        'post_type' = 'jobs',
        'post_author' = get_current_user_id(),
        'post_title' = $_POST['title'],
        'post_content' = $_POST['description'],
        'post_status' = 'draft',
    ));
    wp_set_object_terms($post_id, intval($_POST['category']), 'jobCategory');
    add_post_meta($post_id, 'price', $_POST['price']);
    add_post_meta($post_id, 'time', $_POST['time']);
    if (isset($_FILES['file'])) {
        require_once(ABSPATH . 'wp-admin/includes/file.php');
        $uploadedfile = $_FILES['file'];
        $upload_overrides = array(
            'test_form' = false
        );
        $movefile = wp_handle_upload($uploadedfile, $upload_overrides);
        add_post_meta($post_id, 'file', $movefile['url']);
        add_post_meta($post_id, 'payToSee', 0);}
    wp_redirect('my-ads');
}
