Very stressful and inconsistent work environment. Depending on which coach you asked different answers.
Training is M-F for 7.5 hours a day and times will vary based on location. At my time of hire I got a list of schedules to choose from for post-training, but desirable hours are taken very quickly. It's unlikely you will get weekends off or one of the 9am-6pm slots. However, flexible scheduling, splits, and part-time are options. Expect to work more than you're scheduled in case you happen to get longer calls.
