Here's a nice opportunity for those that are interested! This Saturday (online) is a round of the Google coding competition called kick start. Don't be put off if you're a beginner. It's fine to just participate to get a look at the kind of skills asked for in coding competitions and coding parts of interviews. There's no penalty for bombing out! Google even invite people to interview from it, so its a good thing to get some practice at :) (Its also the last round of kick start for this calendar year)
