I’m going to just give you suggestions on your appearance for the interview because there are several posts that cover the other stuff. What they don’t cover is the first part of the process is basically a beauty contest. Not as in if you’re ugly you won’t get hired, but that if you don’t look like a Pan Am Flight Attendant you’re not getting past the first round. First, clothes: Wear business attire that actually FITS your body in a flatteringly manor. Men: black, grey or blue SUIT (jacket, not vest) with neutral color button up collared shirt. Women: black, grey or blue skirt (just below the knee) and BLAZER with neutral color button up collared shirt or sheath dress (just below the knee) with matching BLAZER (black, grey or blue). PANTY HOSE and CLOSED TOE office appropriate pumps. If you’d wear them to the club, don’t wear them to the interview. You don’t have to go out and purchase and expensive new suit. I found my Talbots black sheath at the resale shop for $14.50. I owned the blazer and shoes already. But they carry those items as well. The most important thing is the way the outfit fits on you. Nothing should be bulging or straining on you. Too big is just as bad as too small. So please find the appropriate outfit in YOUR size. You shouldn’t look like you’re wearing a potato sack or you’re a stuffed sausage. Also, if your shirt collar can’t be pressed to the point it looks brand new, don’t wear it. Get a new one. Raggedy looking collars are a no no. Pack extra panty hose in case you get a run. Second, hair: Men get a haircut and wear your hair in a standard non hip fashion. Think Mad Men. You can be hip after you get the job. Ladies: short hair; comb in a neat and simple manner. Long hair; PUT IT UP in a bun or French twist, NOT a messy knot or pony tail. Hair should be formal military regulation styles. Finally, make-up: Men: don’t wear any. Women: neutral colors. They should enhance your natural features. You are on a job interview, not going clubbing. Wear nude or neutral colors for entire face, including lips. No reds, fuchsias or bright pinks. A light coating of clear gloss is actually the best choice. If you have oily skin, go buy an oil mattifier cream to put on under your foundation. You don’t want to look like your face is about to slide off at any moment. If you’re wearing a white blouse, make sure to blot your chin area so you don’t get make-up on your collar. If you have oily skin or use a heavy amount of foundation on your face, you should really consider wearing a sheath dress to avoid collar mishaps all together. How you LOOK and carry yourself are going to be the determining factors on if you make it past the first cuts. I can’t help you sound professional, but I hope this helps you at least look professional. That’s my two cents, good luck!
