A website editor recalls interviewing a few candidates that "looked fine from the waist up, but then � I spotted their feet on the way out, and they either had really beat up-looking toes or old worn off, chipped polish." That's why "your best bet is to wear closed-toe shoes, so you don't even have to think about it. Toes can be funny things; people's feet aren't the most attractive. You would think 'who on earth would notice my toes,' but the one time you decide to let the grooming slide, your interviewer will look down when handing you your validated parking ticket and catch a glimpse of your toes and think, 'yikes.'" You don't want that.

Tip: Don't blow your chances at the last minute with something as small as grooming your toenails. Bottom line, "If your toes are showing in open-toed shoes, be sure they're well manicured," says a hiring manager. Get these tips to give yourself the best at-home pedicure.

"The place where I work is trying to be more environmental by doing interviews through video conferencing. One of the candidates I interviewed was dressed very casually and had her hair pulled back into a messy ponytail, flyaways and all. It just looked like she didn't take the interview seriously enough to dress up for it, and it gave me a bad impression of her," says a hiring manager.

Tip: Make sure your hair is clean and neat. A website editor advises, "If your hair is in need of a cut, or just isn't working, pull it back in a ponytail so you don't have to fidget with it." Try this how-to for a sleek interview-worthy pony:

Step 1: Apply an anti-frizz product (try Paul Labrecque Curly Style, $24) to your hair, whether it's straight or curly.
Step 2: If your hair is straight, blow dry it with a round or paddle brush to make it extra smooth. If your hair is curly, apply a curl-enhancing gel or cream (like Bumble and bumble Curl Conscious Defining Cr�me, $27) and either let hair air dry or blow dry with a diffuser attachment.
Step 3: Secure hair into a ponytail. It doesn't have to be super tight, but you don't want loose strands falling out, either.
Step 4: For an extra-polished finish, take a small section of hair and wrap it around your hair elastic neatly, then bobby pin the ends under the pony.
Step 5: Run a smoothing product or shine serum over your hair if you have any remaining frizz or flyaways.

A human resources specialist advises, "Don't overdo [your] makeup. Keep it simple; you are interviewing for a job, not going to a club with your friends."

Tip: Look fresh and bright-eyed by applying neutral makeup colors, avoid any dramatic or bold colors. Check out this video on how to apply a perfectly natural makeup look. Or follow these tips:

Step 1: Apply a light-to-medium coverage foundation, then use liquid concealer to cover dark circles, if necessary.
Step 2: For a natural-looking glow, apply a sheer cream blush to the apples of your cheeks using your fingers. If you're trying to look younger, apply a subtle highlighter on the inner corners of your eyes and across the tops of your cheekbones to make your face glow.
Step 3: Define your eyes by curling lashes and applying one-to-two coats of mascara.
Step 4: Add a pop of color to your lips by using a lip stain (try Benefit Benetint, $28) and dabbing a lip balm or sheer lipstick over it.
Step 5: Finish by dusting your skin with a bit of translucent loose powder to set your look.

"This one candidate was picking at his nails and tearing his cuticles during the interview, and he placed each piece on my desk as he was talking. I don't know if it was because he was nervous or something, but how gross is that?" says a hiring manager.

Tip: General rule of thumb: Don't pick. Whether it's your nails, teeth, face or even scratching your head while thinking -- all of these actions show that you're nervous, which you don't want your interviewer to know (even if you are). The hiring manager advises, "You can use your hands for expression, but when you're listening, just keep them on your lap or folded on the table."

"One girl showed up for her interview in shorts and flip flops. One of the questions I asked [was] if she had any visible tattoos (which was important for the position she was applying for), and she said no. But on her way out, I noticed that she had a HUGE tattoo on her calf. Really?" says a hiring manager.

Tip: You know not to lie about your qualifications on your resume, so don't lie during an interview either. Companies need to know that they can rely on their employees to not leak company-related information to their competitors or consumers. And regarding tattoos, the hiring manager advises to "use your best judgment about showing tattoos -- at an artsy company, it's fine, but in a more corporate place, you'd want to keep them covered."
