According to Columbia Business School professor Michael Chad Hoeppner, the popular idea that you have 7 seconds to make a first impression may be a tad too strict.
“I’m not going to give people quite that amount of scarcity, but the beginning really matters a lot,” he says.
During a job interview, Hoeppner says, you have approximately 90 seconds to engage your interviewer’s attention — and how you speak is key.
Clear communication isn’t just about what you say, but how you say it, as Hoeppner attests in his latest book “Don’t Say Um: How to Communicate Effectively to Live a Better Life.”
The way someone delivers information “has a lot to do with how we hear each other, and whose ideas we take seriously or not seriously,” he says.
