One of my first posts writing here was on Glassdoor.com and how you can see your potential future salaries. After being told by a public relations person, they've now opened up the entire Glassdoor.com database for students for free, without having to post anything.
They have a "give-to-get" policy, so ordinarily you'd have to post a review or job salary thus contributing to the database before allowing the person access to the rest of the database. Although this is a good system, students are now exempt from this and can browse at free will and time to thousands of job descriptions from tens of thousands of companies.
Looking for that right company after you graduate is often daunting, but to have a full and comprehensive list of companies and corresponding job descriptions from those who have been there and seen it all, is a great step forward in finding that perfect position for you.
Simply fire off an email from your university email account to and they'll get back to you as soon as possible. Although technically it's available to those with a .edu email address, thus signifying you attend or are part of a US academic institute, I've had it confirmed it is open to anybody with an academic institute email address, but verification checks are made to maintain the integrity of the site.
If you're addicted to Facebook like me, you can add the Glassdoor.com Facebook page to your profile, participate in the polls and keep up to date with the latest and greatest from the site.
If you've seen something on Glassdoor.com that you'd want to share with the rest of the reading symposium, feel free to TalkBack and share the love. Who knows, you might inspire the next future CEO of Apple once Jobs finally gets the boot, or actually dies.
