Beware of CV dumping services, businesses that send your CV to all contacts in their database regardless of whether the contact has an open vacancy, whether they have any positions that match the job seekers’ qualifications, or even whether the recipient is a business or not!
Oftentimes, CV dumping services send hundreds of CVs to the same set of recipients, overwhelming the recipient and further ruining any chance of the job applicant getting a job!
There are plenty of newspaper articles on this topic, so make sure you read up on it. It pays to be informed, to safeguard your time and money.
