The interviewer would like to know how you rate your communication skills and your ability to craft professional correspondence. First, on a scale of 1-10, discuss how skilled you are in communication. Try to avoid giving yourself a 10, as nobody is perfect, and you do not want to come across as overly confident or someone who has no room for feedback and improvement. Alternately, avoid giving yourself too little credit. You do not want to paint the picture that you are a communication dud! Try to remain in a positive range while staying honest and accurate. Use an example of your excellent communication to back your answer.
