Cell phones are an incredible convenience for all of us, but also a major source of irritation when people don’t remember their manners while using them in public places. One of the biggest blunders you can make? Answering your phone while in a job interview!! Seems obvious, I know, but believe me, it happens. If you answer your cell while in an interview for medical sales, pharmaceutical sales, laboratory sales, clinical diagnostics sales, medical supplies sales, pathology sales, imaging sales, hospital equipment sales, medical device sales, biotechnology sales, or cellular/molecular products sales, you can kiss that job goodbye.
