10 ways to lose a job before you get it
Boast and interrupt
Boasting and interrupting are signs of someone who's difficult to work with, says Mark Goulston, the Santa Monica, Calif.-based coach and author of "Just Listen: Discover the Secret to Getting Through to Absolutely Anyone."
But a listening response indicates that you heard the interviewer, what they said made sense, and you're considering it, Goulston says. Use conversation deepeners like, "Say more about ..." "Really ..." and "Hmmm ..." he suggests.
Build off the last thing the interviewer said instead of focusing on your monologue or your memorized elevator pitch. Doing so indicates you're a good communicator and interested in your employer's needs and concerns, Goulston says.
