Firstly you should definitely indent your code properly, and also what ID have you defined DIALOG_JOB as?

pawn Код:

ShowPlayerDialog(playerid, DIALOG_JOB, DIALOG_STYLE_MSGBOX, "Job", "Do you want to join this job?", "Yes", "No");
 
public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
    if(dialogid == DIALOG_JOB)
    {
        if(response)
        {
            SendClientMessage(playerid, COLOR_GREEN, "You accepted the job!");
        }
        else
        {
            KickWithMessage(playerid, COLOR_RED, "You declined the job.");
        }
        return 1;
    }
 
    return 0; 
}
