My phone interview was brutal. I was asked lots of technical questions about everything on my resume.

I wasted time before the in-person interviews studying intricacies of Java, including runtime complexity, obscure data structures, and all of the classical "trick" programming questions, which turned out to be a waste.

The skills test covered Java, Perl, SQL, and Unix, but was ridiculously simple. There were no trick questions, just the basics of each topic.

The interviews featured standard interview questions, followed by lots of proselytizing about the "culture" of GS.
