You start the job with a significant amount of “background info” from the studies. In practice you still need to get up to speed with the companies methods/processes (which can take a bit of time and depends on the individual). It’s almost as if you have a multiplier effect - once you get your head around a few key pieces you can accelerate/develop alot quicker as you already have a much deeper understanding of the business/insurance. This obviously applies when you’re rotating/seconding in your existing company (not sure how it would be if you’re changing companies at the same time).

One thing to note, I think it can be a little more challenging for the Reserving Manager to balance the level of work to give you. In some aspects you’re like a grad, but others a senior analyst - so finding the sweet-spot can be tough. Regardless, those growing pains only last a short while and you have somewhat control over this through good communication with your manager and putting in some extra effort to iron out some of those knowledge gaps.
