7 Things You Should Never Wear on a Job Interview

7 Things You Should Never Wear on a Job Interview Unless you’re applying for a position at Vogue, your ensemble should be a low-stress decision. If you stick to some evergreen rules about what to do (and what not to do), you’ll ensure that you look sharp, without your clothes taking any of the thunder away from your sparkling resume and skills. Here are seven things not to wear on interview day.1. Clothes that don’t fit.If you’re swimming in your power suit, it can make you look a little like a kid playing dress-up. If your outfit is several sizes too small, it can distract from the discussion at hand- and maybe even emphasize some, uh, attributes that really shouldn’t be on the table in a professional job interview. Make sure your clothes fit you as you are. If you can’t afford a new interview outfit, don’t stress- there are relatively inexpensive tailoring options that can make your lucky blazer fit again, or hem those pants so that you’re not tripping over the ends.2. Clothe s that are super-casual.Even if you know ahead of time that the company where you’re interviewing is super cazh, you should still err on the side of formality for your interview outfit. Never wear flip-flops, a hat, jeans, a t-shirt, or anything with an obvious brand written on it. You’ll have plenty of time to wear your casual gear later if the office dress code is laid-back. As for the brands, the only brand you want to be shilling for is you.3. Inappropriate clothing.If it’s low-cut, just say no. If it’s close to that line, find another shirt. You don’t want to spend the interview worrying that if you shift just a little, your neckline might slip down into â€Å"too much skin† territory. The same goes for clothes that are too tight- you want to keep the attention on your resume, not on your risquà ©.4. Clothes that show off your tattoos.For many people, tattoos are in a private (or at least covered by clothing) spot, and it’s a no n-issue. However, if you have one in an area like your lower arm or leg, cover it for the interview. You never know if you’ll be meeting with someone who’s on the conservative side, or sees it as enough to affect their view of you. This doesn’t mean you should necessarily be ashamed of your sweet â€Å"MOM† ink†¦but an interview just isn’t the right showcase. Again, it shifts focus and discussion away from the professional and into the personal.5. Too many accessories.Do you really need that scarf and patterned headband and all of the bracelets in your jewelry box? Short answer: no. Accessories are a great way to show a bit of personality and style sense, but try to limit it to one or two pieces that flow quietly with your outfit.6. High-volume colors.The best overall color palette for your interview outfit(s) is dark and/or neutral. You can still use accent colors, but again- you don’t want your clothes doing the talking for you. The b right plaid tie may be the â€Å"in† color in Esquire this month for its ironic kitsch, but go with the understated version for your interview.7. Clothes that are dirty or ripped.Above all, you should look neat for your interview. If possible, get your clothes dry-cleaned before interview day. But even if you’re doing it at home, make sure you give everything a once-over for stains, little rips, or other imperfections that could ding your composed image while you’re interviewing.Dressing for success doesn’t necessarily require a ton of money- just care and attention that let your best self show through.

Ostrich Egg Shells

Ostrich Egg Shells The broken pieces of ostrich egg shells (often abbreviated OES in the literature) are commonly found on Middle and Upper Paleolithic sites throughout the world: at the time ostriches were much more widespread than they are today, and indeed were one of several megafaunal species which experienced mass extinctions at the end of the Pleistocene. Ostrich egg shells offered protein, a palette for artwork, and a way to carry water to our ancestors over the past 100,000 years, and as such, they are well worth considering a raw material of interest. The Qualities of an Unbroken Egg The ovate eggshell of an ostrich averages 15 centimeters long (6 inches) and 13 cm (5 in) wide; with its contents intact an egg weighs up to 1.4 kg (3 pounds), with an average volume of 1 liter (~1 quart). The shell itself weighs about 260 grams (9 ounces). Ostrich eggs contain about 1 kg (2.2 lbs) of egg protein, equivalent to 24-28 chicken eggs. An ostrich hen lays between 1-2 eggs each week during the breeding season (April to September), and in the wild, hens produce eggs for some 30 years during their lives. Ostrich eggshell is composed of 96% crystalline calcite and 4% organic material, mostly proteins. The thickness (averaging 2 millimeters or .07 in) is made up of three different layers that vary in structure and thickness. The hardness of the shell is 3 on the Mohs scale. Since its organic, OES can be radiocarbon dated (typically using AMS techniques): the only problem is that some cultures used fossil eggshell, so you have to have additional data to back up your dates, always a good idea anyway. Ostrich Egg Shell Flasks Historically, ostrich egg shells are known to have been used by African hunter-gatherers as a light-weight and strong flask or canteen to store and transport various fluids, usually water. To make the flask, hunter-gatherers puncture a hole in the top of the egg, either by drilling, punching, grinding, cutting or hammering, or a combination of techniques. Thats been difficult to identify in archaeological sites, which typically include only a few eggshell sherds. Intentional perforations could be considered a proxy for the use of eggshell as a container, and based on the perforation, an argument has been made for flask use in southern Africa at least 60,000 years ago. Thats tricky: after all, you have to open an egg to eat whats inside anyway. However, decoration on eggshells has recently been identified which supports the use of flasks in Howiesons Poort contexts in South Africa at least as long ago as 85,000 years (Texier et al. 2010, 2013). Refits of the decorated OES fragments indicate that the patterns were placed on the shell before the shell was broken, and, according to these papers, decorated fragments are only found in context with evidence for purposefully cut openings. Flask Decorations The decorated fragments research is from the Middle and Later Stone Age Diepkloof Rockshelter in South Africa, from which has been recovered over 400 pieces of engraved ostrich eggshell (out of a total of 19,000 eggshell fragments). These fragments were deposited throughout the Howiesons Poort phase, especially between Intermediate and Late HP periods, 52,000-85,000 years ago. Texier and colleagues suggest that these markings were intended to indicate ownership or perhaps a marker of what was contained in the flask. The decorations identified by the scholars are patterns of abstract parallel lines, dots, and hash marks. Texier et al. identified at least five motifs, two of which spanned the entire length of the HP period, with the earliest decorated eggshell fragments from 90,000-100,000 years ago. OES Beads The bead-making process was recently documented archaeologically at the Geelbek Dunes site in South Africa, dated between 550-380 BC (see Kandel and Conard). The bead-making process at Geelbek began when an OES breaks, purposefully or accidentally. Large fragments were processed into preforms or blanks or made directly into discs or pendants. Processing the blanks into beads involves the initial drilling of angular blanks followed by rounding, or vice versa (although Texier et al. 2013 argue that the rounding process almost always follows the perforation). Mediterranean Bronze Age During the Bronze Age in the Mediterranean, ostriches became quite the rage, with several occurrences of elaborately decorated eggshells or eggshell effigies. This came at the same time as state-level societies in the fertile crescent and elsewhere began keeping lush gardens, and some of them included imported animals including ostriches. See Brysbaert for an interesting discussion.
