DO NOT MAKE EXCUSES
If you are asked to do an interview over Skype or Gmail call, saying you would rather do the interview over the phone, or that you have a bad internet connection, or even worse, that you do not have Skype or Gmail address, this is a fail. You have just answered ‘no’ to your first interview question. Congrats! If you want this job – find a way to make it work, even if it is not convenient.
You would not be the first person to download Skype or make a Gmail address, create an account, and immediately email your interviewer back with a ‘yes’ and your username. Be sure you have downloaded, installed, and tested Skype app well before your interview is scheduled – the sooner the better. Have video chats with several friends to make sure everything is working properly on a variety of systems.
SPEAKING OF USERNAMES, MAKE SURE YOURS IS PROFESSIONAL.
Anything that is difficult to read or is strange makes a bad first impression. Be boring and use your name.
