How to prepare to interview

You've called for interview. Therefore, the goal of your resume is achieved. I would recommend to follow the rules below before you actually come to the interview:

Research, research and research. You must clearly understand that the company you've been called to is really what you want to work for. There are many links for bad companies, but at least you should verify the following information:
1. What is the product/services of the company and how profitable they are; If not profitable yet, what are the chances to become such in near future?
2. Is it public or private company and who are investors (if any) of the company; For public companies you may extract some financial information at Sedar's site.
3. Check earnings and revenue of the company;
4. What are the plans for the future market expansion, mergers, acquisitions etc.
5. Who are clients of the company and how big they are; is the product/service installed at the client side or just mentioned on the company's list of clients;
6. Who are competitors of the company; How are competitors doing?
Sleep well before the interview. You cannot learn new stuff in the last minute and you should be "fresh" during the interview. Your ability to think quickly and to concentrate on the questions is very important!
Suit is the must in Canada, period. You might be asked explicitly not to wear suit, but I would recommend to take a semi-formal dress code even in this case.
Prepare at least 3 copies of your resume. You never know how many people will participate and you should have your resume handy for everybody.
Read your resume a several times. You should not exclaim "what?!" if the interviewer ask you a question from your resume. Think what might be important for this position and where to elaborate on the potential questions.
Prepare a blank paper and a pen. I bet you will need them! You may put them during interview in front of you and to use when you want to illustrate your experience, to write down the family names and so on.
If you have a computer, refresh your knowledge about the company you are applying to. Scroll their web site and try to remember as much relevant information as possible. You may print this information and to put it in front of you. It is difficult to keep all details in memory and you may lose details when asked about products of the company. In this case you would refer to your papers to refresh briefly the details.
Prepare a list of questions you will ask the interviewer. The question:"If you have any questions" should not be left in silence!!! You must answer this question!
If you have, prepare the references letters or contact telephones.
Be prepared to anything. Have a contact phone numbers of your agent and the interviewer. Do not forget to take a cellular phone, quarters or calling card. I did have a situation when I could not locate a "world leader", hidden in a tiny plaza, my cellular phone was discharge and I had no money to call my agent!
Have company directions. Make sure you clearly understand where the company located, contact maps (http://www.mapquest.com or http://www.expedia.com) Keep a map in your bag which you will take to the interview.
I did not say that, but usually you need 2-3 years of experience even for entry level position. Think where could you get those. :-)
