Got a meeting set-up on WebEx, their own meeting-friendly version of Skype. No video was used and the audio quality was pretty good, though I had some trouble because the HR were British. It started them reading some kind of check-off list including a statement that in order to proceed to the next stage I had to do very well because they have very high standards. Don't be put off by this however because the interviewer was very friend and helpful. Got mixed up with a couple of questions but I had a chance to change my answer. Was a bit nervous and it showed in my English but it didn't affect the scoring, it is the answers that matter so relax.
