So I did the internship a year ago at Adobe. I've been full time there now for 10 months. Here's my advice if you do an internship in sales. Work your butt off. You're not there to party and be a college kid. Act professional at all times, define what you want your brand to be before you go, write it down. Stick to that brand so when people think of you, they think of something positive- hardworking, dedicated, gets the work done when they say they will, etc. Next, learn as much as you can, study, read, record your calls with customers, role play, do everything you can to learn your products and craft your skills. After this, network, network, network. Show up and BLOW UP. If people don't know who you are, then you won't be remembered. You need to have the mindset that you are #1 and others see you as a memorable strong candidate for the job. Get to know your managers, coworkers, and others in company. You need to stand out. How? Do more than expected. Don't wait to be told what to do. Take initiative. Don't ever say, "I don't have anything to do." There's always more to learn, study, help others with, innovate. Be very organized, write down your goals of what you want to learn and accomplish by end of the summer. Then work your way backwards and define what you need to do every week and day to get there. Also, speak up in meetings. Have an opinion. Show your passion. Moreover, be a team player. Help all your colleagues get better. They will in turn help you as well. Be a shark, but still humble. I know this says "one piece" of advice, but if you want to be a winner- give more than you take. So lastly, GIVE! Be a winner, make a decision to be great, take massive action, be consistent, and commit all the way! BOOM GO KILL THAT INTERNSHIP!
