What is funny, after programming professionally for about 30 years, Is I want that job in the call center answering telephones. Even more ironic, it takes 1 month of intensive training to do that job.
In some call centers, you will be following a script about 90% of the time and that takes very little training. In others you actually have to think and troubleshoot issues, those take a bit more time to get up to speed on.
All that being said, I can assure you that you do not want to work at a call center. I'd take whatever programming job you currently have over the call center I last worked at. For whatever reason, call centers attract the worst kinds of managers in this day and age.
Having worked in a call center, I can say with roughly 99% certainty that you do not want that job. It's got to be one of the most mind-numbing, soul-crushing occupations on this planet.
If I could retire today, I'd probably go back to selling video games in Best Buy.
