Any tips from experienced and seasoned devs for a second year comp sci student aspiring to get an internship at Google ? Anything you would suggest I do in general regarding life and compsci and any mistakes I shouldn't make? Thanks :)

I'm a recent graduate and I interviewed at Google few months after my graduation. What I can tell you is, be really comfortable with Data Structures and Algorithms. They don't care if you know agile methodology or not. They're interested in your critical thinking. And practise coding...check out Top Coder and other sites for online hackathons..just practice coding and solving coding problems before you actually start to code.

You also have to sell your soul. I'll buy it for a dollar!
