CAVEAT: Works with scheduled SKYPE calls only.
1) Try to get/borrow a computer that doesn’t whir when warmed up. The agent might ask, “What is that weird sound?” And you might be too nervous to admit your computer is from the Flintstones era. And then you’ll end up more even nervous than when the conversation started.
2) DON'T try to curl up your eyelashes before The Call. The eyelash curler can snap against your eyelid (yanno, because you might press too damn hard since you are so nervous) and that could leave a big bruise right above your eye. AND also leave you half-blind for an hour. Seriously--don't curl your eyelashes!
