Know your algorithms well, searching and sorting especially. Have a good handle on how to write a solid recursive algorithm. In my recent interviews I've encountered a lot of recursion and dynamic programming questions.
Hopefully you have some side projects that you can discuss for the 'softer' side of the interview. These are a great chance to show off both your technical chops as well as communication skills.
The number one advice is to be relaxed and don't stress too much. Keep in mind that when it comes to technical interviews, you don't necessarily have to do perfectly on all the questions and ace every code problem - you just have to outperform the other candidates. I used to get incredibly nervous about interviews and agonize for days over a simple problem that I might have goofed, but then I was pleasantly surprised when I was getting callbacks and offers.
Best of luck to you and be sure to reach out if you want any more info. I am on a tablet currently but I can send you some links to good review material if you'd like.
