A full-time cold caller is someone who spends their entire work day making cold calls to potential clients or customers. This role requires a high level of communication skills, persistence, and the ability to handle rejection. Cold calling can be an effective means of generating new business leads, but it also requires a thick skin and strong sales techniques. Those in this role must have a deep understanding of the company's products or services and be able to effectively pitch them to potential clients. Successful cold callers are able to quickly assess whether or not a lead is worth pursuing and move on without getting discouraged by rejections.
