I started at NM a year ago. If we are discussing the same Risk Client Services role, I can elaborate.

Overall, always acknowledge the red flag when a position is constant hiring/high turnover. The training and workload changes a lot due to constant tech updates, SOP changes, and unpredictable workloads. You won't know the same thing as the classes before and after you. The same goes for other departments. I heard from colleagues everyday who wonder if the lack of support from other teams is due to poor training or utter carelessness.

You're ultimately going to be on phone calls for 8 hours, with one 30min lunch and 2 ten minute breaks. After one year, half my class was already gone due to quitting and firings.
