I worked a job in an insurance company for a client services role. My training consisted of two hours of job shadowing and then being tossed into the fire with a client book of business and getting calls and emails with questions I do not know the answers to.
When I asked about more training, I was told “ask questions”. But how do you know the right questions to ask? Clients/customers were getting mad at me. I was losing sleep and having heart palpatations. I stayed a year. I don't know how I did it, but it took a lot of faith. Luckily, after leaving that job I am at a better job with a full training manual/checklist.
