I got a call from them also. You have to say "put me on your do not call list" or the interviewer is not allowed to remove your number. They can get in trouble with their bosses...
These people call at least once a day, for the past several days. I'm tired of their interruptions during the day (and sometimes night.) These people should be fined if they continue to call after they're told not to. I haven't answered one of their calls yet, but I will soon, and I will tell them to STOP calling!!!
