When applying for a new job, you’re probably savvy on submission details. After your application is on its way, however, your task is not over. Why? You need to follow up with your target employers for two reasons: to make sure your materials reached their destination and to reiterate your interest in the position.You can follow up by phone, email, snail mail, or even in person, but as you do so, be conscious of these common mistakes. The following simple follow-up blunders can undermine your credibility, and possibly cost you the position.Remember the detailsKeep a log of each employer you reach out to during your job search. In the beginning of your search, it may seem impossible to confuse one position title, post, or employer with another. But after your 25th application, you will understand the logic of tracking. When positions and managers’ names start to blur together you’ll be less likely to skip a step, forget to follow up, or attach the wrong manager’s name to the wrong company. Be mindful It’s important to be aware of your actions, and how they may be interpreted. Enthusiasm can make us go overboard, so keep a clear head at all times. Watch your tone in your communications. Letting an edgy or demanding inflection come through is rude, and can ruin your chances (and, possibly, your reputation) instantly. Remember to be considerate of the timeline provided to you. For example, if you’re told you’ll receive an answer in two weeks, don’t reach out before two weeks have passed. Sending gifts, food, or flowers to your manager’s office is unprofessional and unethical. This goes without saying, but sending these things to a private home is absolutely off limits. Remember to mention key credentialsWhen you follow up, keep your messages concise but don’t edit yourself too much. A follow-up is a good opportunity to fluff your professional feathers. For example, if you achieve a major accomplishment while you’re waiting to hear back, share this news. If you forgot to note an honor, experience, or skill set in your application, mention it in your follow-up note. Don’t let it fall through the cracks. Sometimes these add-ons and afterthoughts can be enough to sway the decision in your favor.
