Many companies use Skype to conduct job interviews. While it makes the interview easier because you don’t have to travel, it also creates new challenges. If you’re looking for a new job and expect to do Skype interviews, these tips can help you look professional when it comes time to chat with your potential future employers.

You want your interviewer to see you, so don’t sit with your back to a bright light. Your webcam will likely adjust to the lighting and make you look like a mysterious silhouette. Your interviewers won’t see your face or mouth move, and it won’t improve your chances of getting the job. Instead, turn toward the light source if you can, so that your face and background are equally lit.

If you’ve ever been on the other end of a call and heard everything you said echoing, you know how frustrating that can be. Some high-quality microphones do a great job of preventing this. The easiest way to make sure you don’t annoy your interviewers is to wear headphones. Unless you have incredibly loud headphones, your microphone shouldn’t be picking up your interviewers’ audio.

When you interview via Skype, your interviewer may only see your chest, shoulders, and face. Still, you should dress appropriately for the interview. Dress as if you were going to the company office to meet your interviewer in person. Wear slacks or a conservative skirt, as you may need to stand up and move around during the interview. Shoes and socks are optional; if your feet end up on camera, something else has gone wrong.
