I had a skype interview with a potential employer and it went so well that they paid for me to fly down to Canberra when i landed in Melbourne the following week.
Treat it like a proper job interview, and i would recommend the following:
Check time of interview, i was expecting it at 10 pm, they came on at 11.
Make sure you`re fresh and alert..maybe have a shower and coffee beforehand.
Have a glass of water at hand...in case your mouth drys up due to too much talking.
Make sure your`e in a quiet place and won`t be disturbed.
Double check you have sufficient credits in case you have to call them back etc.
Copies of CV, Job ad and notes and pen and paper etc
The above might sound blindingly obvious, but it can be easy to forget the small things lol
The job i went for was a sponsored one, i flew to Melbourne to see 7 potential employers.
This company was the first i saw, picked up at the airport, went to the company and met the people, then out for dinner,following day picked breakfast and a quick drive around Canberra, final chat before leaving.
AND THEY OFFERED ME THE JOB THERE AND THEN...
Got my visa approved last Friday, landed back in Manchester Sunday night, packing up and flying there in 3 weeks for a new start.
Hope everything goes well for you
