Telemarketing 3-19-25

I was an unsuccessful telemarketer, back in the 1990's, before there was caller ID, the internet, and cell phones.I forgot to mention that I also set up appts for a Janitorial Services Company, which I got fired from after a few weeks.But I still have the memories, the experiences of cold calling strangers on the phone, strangers who wanted to get rid of me as soon as possible. Coupled with cattle herders walking the floor in the room, making sure that I keep smiling and dialing and do not engage in conversation with my "neighbor" I still remember those days, do not know what it is like to be a telemarketer today, and I am somewhat curious, would I be more successful today? or even worse?
