I liked that I finally got to apply my electrical engineering skills in a co-op position. Previous experiences did not really give me the same opportunities to apply the knowledge I learned. Also I worked hard on a project to bring it from start to finish and launched it into industry use.
What I wish was different
I guess it would have been nice to have side projects in addition to my main project to break my work focus up.
Advice
For your first co-op be open to any position you are qualified for. After getting through a rotation or one block, then start to get pick. After you have experience, DON'T SETTLE, go for what you dream to do, no less!
