How to find Companies Telephone's number?
I'm operating in the Digital IT area and there are many talented candidates which received too many InMails, messages, contacts, that they won't reply to any proposal. So I need to go back to the classic headhunting call to the candidate's company. Now...this is the challenge: there are a lot of companies which have no numbers to call. I mean, there's only the Customer Service number, but I can't find the telephone's contacts of offices.
Is there any tool, list, contact center...which I can use to find out companies' numbers?
Thank you so much!
