Cold calling can be challenging and uncomfortable. Talk to the hiring manager about the cold calling experience you have and be sure to talk about any successes that have come along with that. Include numbers and percentages if you can. The proof is in the numbers!
"I have been in a cold calling based role for the past 3 years, and with great success. My level of comfortability with cold calling is strong. In my current role I am responsible for cold calling up to 100 new leads per week with an expected conversion rate of 15%. My current conversion rate is 22% which I am very proud of."
