Using your phone as a tool for recruiting is becoming increasingly difficult.

According to researchers, people have stopped answering their phones because of the high volume of machine-based fraudulent calls.

In the United States alone, over four billion spam calls were placed to mobile phones in the last year.

This means over 40% of all calls to mobile phones are initiated by machines and robots.

And here’s the surprising part—the rate of unwanted calls was only 3.7% in 2017.

Why the drastic increase?

Because scammers are getting better at tricking people to answer their phones through techniques such as “neighborhood spoofing” where the inbound caller ID looks similar to your phone number.

Once burned, twice shy.

Unless the call is from someone who is a known contact, many people are choosing not to answer.

It’s important to diversify your recruiting techniques as the technology landscape changes.
