ANSWERING YOUR CELL PHONE: If you're like many busy professionals who never turn off their cell phone, a job interview is the one time that you should make an exception. Ringing and vibrating cell phones are totally unacceptable during an interview. And by all means, donâ€™t add insult to injury by actually answering a call or responding to a text message. Itâ€™s best to always give an interviewer your undivided attention, even if they donâ€™t extend the same courtesy. Ringing cell phones are interruptive and can break the flow of a good conversation. So, turn your cell phone completely off before entering the interview. Hopefully youâ€™ll have good news to share once you turn it back on.
