Pros
The ONLY pro is that they'll hire anybody pretty much anytime with half a brain. So if you were desperate for something it could fill the gap between "good" jobs.
Cons
Tech Coach was created to take the burden off the carriers when it comes to teaching dumb people how to use their smart devices. So, as part of your cell phone insurance you get a poorly trained millennial who checks things off a guide. My experience is from the top down they are basically willing to do or say anything to make the carriers think it's a great product. I worked for Verizon who IS a good company for nearly a decade before doing the tech coach thing and was appalled at the level of immaturity and "deceit" they used at Asurion to maintain their contracts with the carriers. Basically it's just a bunch of people who needed a job in a city full of call centers. I think I still have nightmares about it from time to time. The interviews were jokes. The training was the biggest waste of time and money I have ever witnessed. The management was awful.
