Tesla

Exciting, fast-paced environment. Lots of responsibility and opportunity for growth. Interns are treated like full-time employees and are expected to perform as such.

The culture embraces challenge and explores opportunities to change the industry through new technologies and methodology.

Fun work culture, work hard, play hard. Teams are really close and positive.

Long hours (Must be willing to stay late some nights and work some weekends, but it comes in waves.)

It's not for everyone. You have to genuinely care about your work and be passionate. If you're not having fun every day, then you need to move on to something else.

Make sure to acknowledge the long hours and hard work that employees put in without request. It significantly boosts morale when everyone feels appreciated. It's the little things that go a long way. Just say "Thanks for your hard work, it does not go unnoticed."

(My manager and mentor does this regularly.)
