Tell us about the most difficult customer you had to tackle with.

As an account executive you will have to talk to many customers daily. Many times you will have to face the difficulty but you must have done something to tackle with them. You will have to explain one such incident in front of the recruiting panel. Make sure that you do not stop while answering to this question. Just explain the incident breathlessly. If you will stop then the recruiters will have a bang in you. And yes, be prepared for some cross questions.
