I just got done talking to the insurer for my new job. It was very informative and painful, and was a quick reminder of why I am glad I fly airplanes for a living. There is such a thing as an open pilot warranty, this means anybody having these flight times is covered under the insurance policy. For a king air 350 it is
3500TT
2000 ME
KA 350 School in 12 months
250 in type.
I imagine it is something similar in a 200. They can also add someone to the policy individually, your name will be listed on the insurance as being covered, even though you don't meet the open pilot #s. Your boss will have to submit a pilot experience forum to the broker, who will take it to the underwriter, who with your times may approve you or not. As an example I was approved with no KA350 experience just 350 school. My guess is if you impressive during the interview they would make it work.
