The end of the resume? Hiring is in the midst of a technological revolution with algorithms, chatbots

The last time Chuck Blatt searched for a job, about 10 years ago, he relied on a thoughtful cover letter, a resume printed on nice paper and good rapport during a face-to-face interview.

Now, he said, "that is all out the window."

Since Blatt, 50, left his job as vice president of a painting and construction company in March, he's spent nearly every day in front of the computer in his Chicago home applying for jobs via automated processes.

He uploads his job history with the click of a button. He records videos of himself answering automated interview questions. He takes the lengthy online personality tests employers use to screen candidates.

Blatt, who is seeking a marketing position, says technology makes it easier to apply for more jobs. But other parts of the high-tech hiring process leave him uneasy.

"I have been turned down for positions that I thought I would be perfect for," Blatt said, and it is often impossible to know why. "There is no feedback because there is no one to talk to."

Technology is transforming hiring, as employers inundated with applications turn to sophisticated tools to recruit and screen job candidates.
