I really enjoyed being able to work on two different real engineering projects. One was self driven and I liked that they gave me the freedom to do something I wanted for them (on top of what they needed me to do).
What I wish was different
I wish the location was different. However, the work itself was great!
Make an effort to reach out to friends, family, neighbors, and other people since it is hard to get an internship after your sophomore year. Networks are important.
