When inviting a candidate to a skype interview, make sure that you write the subject line clearly mentioning the intent of the mail. If this is not clear, then the candidates will not even open the mail. Apart from mentioning the intent, it will also be important to mention all the details in the Skype interview invitation mail that will help candidates understand how to join in for the interview.
