Career fair update:
At the fair I bee-lined right to a company I'd talked to at a hackathon before. The person I talked to there was extremely enthusiastic, and called me a "really strong candidate," and even talked about providing housing for the summer near the workplace!
I'm contrast, AMD's interviewer looked extremely uninterested. Pretty sure they just grabbed some random engineer who didn't want to be there.
Microsoft had a line so long that the fair ended before most of the people even got to talk to Microsoft. Needless to say, I didn't even bother.
Qualcomm seemed cool, that went alright.
Overall, really happy with how the fair turned out, and really excited with how likely this job looks for me.
