First things first: Be reachable. Clear your voicemail inbox and record a professional greeting in case you miss a call. Upgrade from that old “firstname.lastname@example.org” account, and try for a more business-friendly address with your name in it. Check and double check your phone number(s) and email on your resume, cover letters, and LinkedIn accounts. It may sound simple, but it is too important not to mention, be sure that you’re reachable.
