The function redirect was not found. Maybe you did not declare it correctly or list all dependencies?

                break;

break is not strictly necessary here and could be removed.

            case 'submit':
                return redirect()->route('job.application.complete', $jobPoster);
                break;
            case 'previous':
                return redirect()->route('job.application.edit.4', $jobPoster);
                break;
            default:
                return redirect()->back()->withInput();
        }
