Facebook, Instagram, and Twitter
When thinking of how to integrate social media outlets into your professional life, be cautious of what you post. Review your privacy settings and remember that potential employers can access your site through shared friends, interns, and other personal connections. Be sure that the groups you like and the photos you share reflect a professional image that you would want to share with a potential employer.
Facebook, Instagram, and Twitter can give good insight into your daily happenings. If all of your posts and/or tweets highlight your weekend activities, think again about how you use these applications. Remember that posts can come up on internet search results. A good piece of advice, don't post anything online that you wouldn't want to see as the headline of tomorrow's newspaper.
