Well, first of all, you have to know if you really want to work at what ever you apply for. Make sure on your application that you did not skip anything. Never leave a blank on the application. If you are at a job interview, make sure that you are dressed appropriately and if you have any tattoos, be sure not to show. No chewing gum, Also have your phone turn off or on silent. Always be friendly and never ask about the amount you will get paid and don't ask about vacations. Be sure to speak clearly so the person can understand you. If your a boy, make sure to look clean. You can ware dress pants and a nice button t-shirt. DO NOT ware shorts,t-shirts, flip-flops,or sweaters or sweat pants, also do not ware any perfumes or body fragrances. Be sure you are on time say for example if your interview is at 12:00 pm, be their around 11:40 or 50 pm. Never go there early. Trust me!! LOL. During the interview, always smile and look happy. When its over, shake the persons hand and leave with a smile. I hope this answer is helpful to you and Good luck getting the job!
You go to whichever job you want to apply for and ask for an application, then fill it out and then return it. If they like what they see they will call you. If you really want to impress them give them a resume too.
You go to a job you like and get an application. They will hire if you if they are pleased with it. You can send in a Resume. They will also call you for an interview if they are pleased with what you said then you are hired!
