Maybe timing is not right, but if you want to test your programming skills against other talented people you may want to register for Google’s programming contest CodeJam 2010. It’s fun (if you like programming challenges) and you’ll realize how much you need to learn.
I usually join the contest and I am kick out very soon. Java is among the programming languages accepted. There are many sample problems you can attempt to test your skills before the contest begins. Those of you making it to Round 2 can claim an extra 10% mark.
