One suggestion is to avoid choosing only the largest companies. Choose a range of businesses including small to medium sized companies. After you have chosen your companies try to find out as much about them as possible. If possible try to find out the names of any key personnel.
You need a CV, and a Letter of Application (cover letter). Both documents should contain words and phrases that indicate knowledge of the industry. This can differ not only between industries but also between companies.
The letter of introduction is important as potential employers will often read this more closely than a CV because it is an edited and highlighted version of your CV. This ought to give a snapshot of your reasons for seeking employment in this particular organisation. A useful approach is to say that you are interested in “future opportunities”, this does not require an immediate yes or no response but allows the
potential employer the opportunity to consider future or current employment requirements. You should also invite a meeting at a later date e.g. “I look forward to an opportunity to briefly meet with you to discuss future possibilities with your company”.
