I was able to work in a field directly related to my studies. I contributed to software projects used by thousands of people across the country. It was a great learning experience and it created opportunities for me when I graduate. I made business and personal connections that will only improve my career prospects.
What I wish was different
I can't thing of anything I would want to be different about my experience here this summer.
Work as many internships as you can. It helps to know whether you'll enjoy working in the fields related to your studies. When you work, don't think of yourself as an outsider. The people that hired you saw something of value in you, so work hard.
