Make the most of your university:
Your uni isn't just an expensive place to spend three years locked away from sunlight in an engineering lab. It's also likely to be a hotbed of research that is often called upon by engineering firms to collaborate on exciting new technologies.
As such, your lecturers may be able to give you the lowdown on different companies and relate their own experiences working for them. In fact, it's not unusual for engineering firms, especially interesting startups, to get in touch with universities they've worked with in the past to search for new recruits for graduate jobs.
Do check out your career center. It sounds obvious but a lot of people don't look there. As well as job listings and other information, career departments often provide personal advice sessions and coaching in skills such as interview technique.
