A lot of people want jobs in marketing, which is great news for those of us currently hiring. However, after a decade of screening, interviewing and onboarding marketers, there are still some mistakes that I constantly see. Here are examples of some mistakes you should avoid.
1. You use a Hotmail or AOL email address
Marketers should see into the future, not live in the past, so unless you're applying for a job as a historian for 1999, I would suggest updating your email address, perhaps to a Gmail address. Bonus points if you use an email address associated with your own custom domain because it shows you know something about using the web and technology.
2. I can't find you on Google
You don't have to be popular like Michael Jordan or Michael Jackson, but you should be present enough on the web that I can easily find your LinkedIn profile, content you have created, your Twitter account, or your personal web page just by typing your name into Google.
3. Your last tweet is from 2011
Don't tell me you’re a digital guru if you haven’t tweeted in the last three years. You don't have to have a million followers (though I'll pay closer attention if you do), but you do need to be participating in the conversation on a regular basis by sharing other people’s content and staying current. A few tweets a week is enough; a month long lapse is unacceptable. I’d rather see you using one network well and not have accounts on the others, than have accounts everywhere and use none of them effectively.
