Answer 1

You forget the menu slug hence you getting error .

add_menu_page("Jobify Menu", "Jobify", "manage_options",$menu_slug, "jobifyAdminMenu", null, 3); 

For example :

add_action( 'admin_menu', 'register_my_custom_menu_page' );

function register_my_custom_menu_page() {

    add_menu_page( 'custom menu title', 'custom menu', 'manage_options', 'myplugin/myplugin-admin.php', '', plugins_url( 'myplugin/images/icon.png' ), 6 );

}
