Sometimes it’s best not to imitate what you see on TV and the Internet (great advice, I know), especially when it comes to fashion choices for the workplace.

Facebook creator Mark Zuckerberg is well-known for promoting his social media juggernaut while sporting hoodies or dark grey t-shirts. And those young technology creators in the new Samsung commercials are dressed down in jeans and t-shirts while discussing their “Unicorn Apocalypse” phone application.

While Facebook has been wildly successful and those creative geniuses look like they are having a blast deciding whether or not the unicorn zombies should have glitter in their manes (I couldn’t even make this stuff up if I wanted to) – it’s best not to expect a relaxed atmosphere when interviewing for IT jobs.

In fact, a recent survey from Robert Half Technology says IT professionals seeking a new job in Indianapolis should interview in a suit if they expect to be taken seriously. Almost half of Indianapolis chief information officers (49%, over the national average of 46%) cited a formal business suit as the appropriate interview attire.

If you don’t have a suit, khakis and a collared shirt were preferred with 34% of respondents; tailored separates were then preferred by 14% of the CIOs interviewed nationally. Only 4% of CIOs expected anyone to show up wearing jeans and a polo shirt.

Of course, the point is to let your skills and experience shine – so don’t overdo or try to be ironic by showing up in a tuxedo with tails or ball gown, either.
