3. Tweet like a professional You are what you tweet - so be mindful of your tweets and comments if you are here to impress the hiring managers. Your online persona should represent you as a professional individual who has unique and valuable thoughts to contribute. You can easily create such an impression by sharing industry related links that are helpful to your followers and by commenting on the latest industry news. When you sent across a message that you are keeping up with the industry trends, you will have employers knocking on your doors.
