Interview Dress Code

Often when you need to learn how to tie a tie it is because you have to show up for a job interview in the near future. To help you along and get the most out of your tie knot I put together this page. At a formal job interview, one of the things you want to project is confidence.

However, while the tie knot is a very important aspect of your job interview attire, your overall appearance counts as well. Hence, it is important to understand what makes up your entire conservative job interview dress that is still the standard in most corporations.
The following list should give you a good idea of how to dress for a job interview:

• Suit: A conservative, two-piece dark grey or a dark blue business suit would be the ideal suit to wear on the day of your job interview.
• Shirt: A white, long-sleeved dress shirt that is neatly pressed and has a good fit is recommendable.
• Tie: Go for a plain colored, non-distracting, conservative dark blue or dark red necktie made of 100% pure silk.
• Tie accessories: A classic silver tie bar ensures that your tie is held in place during the interview. Without one, you often end up adjusting your tie several times during the interview, which will make you look nervous.
• Shoes: Clean and polished conservative dress shoes, black lace-ups if possible, would be your best choice.
• Socks: Dark socks, black if possible, would be ideally suited.
• Belt: The belt should match the color of your shoes, so go with a black one if possible
• Hair: Make sure that you get a well-groomed hairstyle before the interview. Be aware that short always fares best in interviews.
• Beard: A beard needs to be shaved off.
• Mustache: Mustaches are a possible negative, but if you must, then at least make sure it is neat and trimmed.
• Fingernails: Ensure that they are clean and trimmed.
• Rings: Wedding or college rings are generally acceptable but other rings are not.
• Earrings & piercings: Both earrings and visible body piercings should be taken out on the day of the interview.
• Body odor & fresh breath: Make sure that you do not smell badly and chew some gum before the interview, yet never during the interview.
• Perfume & cologne: Keep perfume and cologne to a minimum.
• Briefcase: Take along a briefcase with a notepad and a pen for any notes you may have to take during or after the interview.

Realizing that this list is quite exhaustive, I still think that you should try to make effort to ensure your job interview attire resembles the one above. Remember, it is almost always better to be higher than the standard than lower. In the end, you are interviewing for your future so every additional effort that sets you apart from your competitors will benefit you eventually.

Consider putting all your clothes on the day before the interview to get an idea of the "big picture", especially if you are not used to wearing formal clothes. In that case, it is better to feel a bit awkward the day before the interview than on the day itself.

How to Tie a Tie ?

While this tie knot can be worn by anyone, it looks especially well on men with shorter necks as the knot's rather narrow and elongated form stretches the perceived height of the neck a tiny bit.

Watch Four in Hand Knot Video

Let's walk through the Four in Hand Knot step-by-step, using animations first and then a real-life demonstration of tying this necktie knot:

 

Step-by-Step Four in Hand Knot Instructions

To tie the Four in Hand Knot, select a necktie of your choice and stand in front of a mirror.
Then simply follow the steps below:

		1) Start with the wide end ("W") of your necktie on the right, extending about 12 inches below the narrow end ("N") on the left.
		2) Then cross the wide end over the narrow end.
		3) Turn the wide end back underneath the narrow end..
		4) Continue by bringing the wide end back over in front of the narrow end again
		5) Then, pull the wide end up and through the loop around your neck.
		6) Hold the front of the knot loosely with your index finger and bring the wide end down through the front loop.
		7) At last, remove your finger and tighten the knot carefully to the collar by holding the narrow end and sliding the knot up.

That's it! That is all there is to the Four in Hand Knot. You will quickly learn to tie this necktie knot in less and less time every time you practice it. Just keep going, my friend!
