Unisys Customer Service Representative interview questions

Can you describe a situation when the client wasn't satisfied and how did act in that situation? Imagine that the client is angry and starts to shout at you, what would be your reaction? If you have a conflict at your workplace how would you solve it?

Beside the introduction and general questions about me, my motivation, experience, etc., there was an emphasis on the question that why do I choose the field of IT, what are the attributes of a good team player attitude, and what are my further ambitions at the company - would I choose a team leader, a level 2 agent or a senior position later on.
