One of the best ways to help you decide what you want to do. Or if you have already decided, you will need to gain some kind of work experience (now more widely known as an internship) to put yourself in the best possible position to secure your dream job.
Finding them is not too difficult given technology and search engines available. Securing one is a little more tricky. Competition is intense.
Applications processes vary from direct letter, application form to an on-line application. Make sure that you are aware each company’s application policy.
Remember you need to apply for these internships early and applications may require a great deal of detail and take a long time to complete. So allow yourself plenty of time.
