After my online application (and online tests) I was invited to the telephone Interview stage. The interviewer was very friendly but at times sounded impatient which is i found a massive downside to a telephone interview (as I start interpreting his voice in absence of body lagnguage).
Do not be discouraged or intimidated by that.
Stay positive, because that will be reflected in your own voice.
Questions are not difficult (especially because they can be found all over different forums), but you need to
keep your answer slick.
Get to the point without leaving crucial information out, and don't forget to talk about a "Solution/Conclusion". What did you learn/do after you situation?
The interviewer asked one question per competency and asked me about details on my answers. I didn't answer one of the questions really well, and in another one my answer was fairly long so he interrupted me. I thought it didn't go particularly well but I got through to the AC.
Hope everything goes well for you too. =)
