1. Do not go out the night before your interview. Relax in the evening, go to bed early and take a shower in the morning.
2. Appearance / Wardrobe:
No piercing! Yes, no piercing and that goes for nose, eyebrows, lips and tongue. The only place piercing is acceptable in business environment is ears and that only goes for females. No jeans, no tennis shoes, no shorts, no flip flops and no chewing gum!
Women: Avoid aggressive make up, red lipstick or colorful and bright clothes. No need to wear a suit if you do not like it or do not have one but conservative type business attire is more than welcome. Do not overdress and do not wear strong perfumes.
Men: Put on a clean shirt (ideally white) but iron it before you decide to wear it. Choose conservative colors for the tie. If possible go for a navy color suit. If you do not have a navy suit choose a dark suit if no dark suit go and buy navy suit. No brown shoes.
3. Visit the website of the company in question. Check what they specialize in, where they have their offices, etc. Try to gather as much information as possible. Search for the most recent news regarding the organization. Knowing this will help you strike conversation or answer questions when asked what you know about the company you are visiting.
4. Try to find out as much as possible about the people you may meet during your interview. Check LinkedIn or XING for more information and learn about their professional background and education (you are “in trouble” if you do not know what LinkedIn or XING is). If they are not on any of the professional social media, improvise.
5. Do not be late! No one cares that there was traffic or that you could not find parking. Unless absolutely necessary avoid calling the company asking for directions. You should know where you are going and if you do not trust your sense of direction or do not have Navigation (GPS) in your car go by the office where the interview is going to take place the day before to know exactly where it is. Do not arrive too early either. Being 20 minutes early is more annoying than being 10 minutes late. You should be in front of the building 10 minutes before the time of the interview. Ring the bell 5 minutes till.
6. You will most likely be nervous before and during the meeting but make sure you do not have sweaty hands when you are to shake hands with someone.
7. It is important to ask questions during the interview. Prepare a few to choose from. You can write them down and bring them with you but if you go for a single sheet of paper make sure that it looks professional and is only folded in two.
8. Do no talk too much but most importantly concentrate and listen to the questions. When answering them do not talk around the subject. In other words get straight to the point but do not be too affirmative. Avoid corny and cliché statements.
9. Do not pretend to be someone else during the interview. If you do not get the job you will know you were not right for the role but if you are hired you will feel great.
