The thing I liked the most was the flexibility they gave me with my school schedule. Next would be the amazing opportunities given to me by their Research Department.
What I wish was different
I honestly would not change a thing. It is a steep learning curve but the most valuable asset to my developing career.
I would say that anyone looking at a mechanical engineering internship should be ready to handle stressful situations, talk to important company team members and to try and never back down from an opportunity. I would never put yourself in a situation you cannot handle but do everything in your power to push yourself to bigger goals and challenge yourself. Talk to high ranking company members like they are on your level but always be polite and give them the up-most respect. Be a good listener and always be eager to learn more.
