1. Recently, employers have shifted to video interviews, especially via Skype. You have to be ready with a good internet connection. Place a good lighting. Rehearse and be familiar with looking straight to the camera. Dress appropriately.
2. Be honest and straightforward. Most employers conduct multiple levels of interview, especially for high ranking positions. Be ready with an honest answer to questions that pertain to your weaknesses. It is more likely that your interviewer has prior contact with your character references.
3. Act according to your age. Your knowledge of technical terms would give away your ability to adapt to the changing environment in the workplaces around the world.
4. Most employers place emphasis on productivity, so be armed with samples of projects that can back up your work experience.
