What I wish was different
Some other interns didn't have managers as awesome as mine and they felt like their time at the company wasn't worth much, or that they weren't contributing in any meaningful way. My own work was mostly organizing data with excel sheets, drafting documents in word, and a LOT of reading. Little to no engineering design work.
I wished that I didn't have to deal with the LA traffic to go 30 miles into work every day and night (~1 hour in the morning and ~1.5 hours at night), but it was worth it.
