If you want for example to redirect the user to the home url if it’s not have admin permissions?
Here the code:

function my_login_redirect( $redirect_to, $request, $user ){
    // Is there a user to check?
    if( is_array( $user->roles ) ) {
        // Check if the user have admin permissions
        if( in_array( "administrator", $user->roles ) ) {
            // Redirect to admin
            return admin_url();
        } else {
            return home_url();
        }
    }
}
add_filter("login_redirect", "my_login_redirect", 10, 3);
