Especially those who got GE, what do you think you did to get GE?
XFN
The above comments are completely correct, but also try to finish your base project 1-2 weeks early. This allows you to have time to really have impact beyond your core project. At least for me, my team had two other sister teams, and so it was easy for me to make my project XFN. You gotta grind it out tho, I was on track for GE until I started working 11-4 and I took a week off to travel with my gf. I ended with EE lmfaoo
I was a SWE intern working on core infrastructure. I chased down impact pretty aggressively. Ended up with a laundry list of impressive-sounding statistics about speeding up such-and-such, which was enough to get GE. Ask your manager what you can do to go above and beyond. Make clear that you don't want to be a typical intern, you want to show what you're capable of. EDIT: Also some XFN work
Also got GE as a swe intern. Can confirm this is exactly what you should do. Great comment @wbt
