Programming Assignment - what's important?

What in particular is a company looking for when they send out programming assignments. What should I optimize my code for? Readability? Code style? Efficiency?
After a long history of private and open source game projects and with a M.Sc. in CS in the bag, I am currently trying to break into the industry.
Some companies hand out programming assignments to be solved by the applicant. I recently had one of those and my application was turned down without further information. I even followed up with another email asking for feedback, which they ignored.
This time I'm awaiting a programming assignment from another company. It's a highly reputable studio, one where I really, really wanna work. Had a phone interview conference with three of their senior programmers which went extremly well. But next up is a one day programming task. And I'm really uneasy about it. What do you think I should focus on? Finding an optimal solution? Or writing pretty and readable code? Anthing else?
Thanks for any input!

I would just do a normal code review: Does it work? If it doesn't work then nothing else matters. Next, what kind of problems are there with the code? Does it potentially follow null pointers? Does it potentially divide by zero? Does it potentially break numeric limits? Did you use magic numbers or named constants? Is everything initialized to sane values? Are any resources leaked? Etc., etc.
If you have to focus on anything, that one thing should be maintainability. Can someone else come in and tinker with the code safely? The answer should be yes.
Don't let the first interview get you down. You will probably need to interview at multiple companies before you eventually land the job. That is normal.
Good luck on the job hunt.

How you approach the solution is largely based on your own style -- but you want to think about simplicity, maintainability, extensibility, and performance, to name a few.
Its acceptable to prototype and throw away code too, providing you can do it and complete the assignment in the allotted time. As Frob said, maintainability is probably the one key thing if there were only one; alas, its always a balance, so a solution that achieves great maintainability at great cost to simplicity or performance is probably not the solution they are looking for. In the end, their judgement is going to be subjective, so don't get so caught up on any one aspect that it begins to cost you time.
And don't forget to reserve time to test your solution.
If you should find yourself with extra time, go back and make sure you've commented correctly and thoroughly, and perhaps provide some light documentation -- outline the approach, discuss your design options and decisions, talk about performance and storage requirements. Even if they don't ask for this last step, it will be valuable as an orientation for reviewers and demonstrate how you communicate technically, so do it anyways, time permitted. Keep it brief, but no briefer than need be. If you can give the impression that you can communicate technical information in impromptu meetings around the water-cooler, its a very desirable quality.
