Once you've decided to pursue engineering as a career, you should start preparing for the necessary hurdles such as phone interviews. Though any interview is a good interview, phone interviews should be dealt with extreme care. You're already at a disadvantage because you don't have the automatic benefits of the physical first impressions such as professional dress and a firm handshake. Instead, all you have to rely on are your resume, portfolio, voice and words. You have plenty to work with as long as you prepare. Have a copy of your resume and portfolio in front of you before the call starts. If the Internet is available, pull up their website, but be careful not to get distracted during the interview.
