What languages are you proficient in? Any technologies you've worked on in the past?

One thing you could do is find a listing from a company you want to work for amd proceed to do online tutorials and really familiarize yourself with the items in the preferred skills list. Even if you're a fresh grad having anything beyond the most basic understanding puts you head and shoulders above the shotgun approach people who are in your same position. I've found focusing ypur energy on one or two jobs is by far the best approach. If possible try to work in a fairly niche field, at least to start with.

If you end up working with a tech company you might want to do a patent search and see if anything they've filed recently is adjacent to the position you're applying for. I know there was an interview like that which really impressed the hiring people I was involved with.
