I am a medic in a consulting firm.
Personally I prefer it to clinical medicine.
A few points, don't have much time:
Pros (for me):
1): The work is varied and interesting (not always but for the most part)
One month I might be assessing the commercial viability of a new product, the following devising a go-to-market strategy in Europe, the one after that assessing the oncology market, or the CNS market, etc etc. It is a good blend of the things I liked about medicine and the things I find interesting in business.
2) The people are intelligent without fail (at least at my firm) and there is none of the politics and nonsense that pervades the NHS - there is no dealing with idiotic nurses turned managers. Nobody has a clipboard and no real job - there is no dead wood
3) We are looked after. If I work late I get free food and taxis. I no longer have to survive on Mars bars overnight.
4) I am paid a lot more. However I am relatively senior - I know other doctors that took a pay cut.
5) I have options to do other things after consulting that I would never have even thought of before.
1) If you are not in a top firm I imagine that little of the above applies. I can count on less than one hand the number of firms I would consider joining if I had to do it again.
2) Once you leave it will, I imagine, be very difficult to go back
3) Travel - business travel is not all it is cracked up to be.
4) You will probably miss some of the camaraderie and seeing patients side of medicine
5) And most importantly, you have most likely missed the boat by a year or so - I very much doubt anyone is hiring at the moment. We certainly wouldn't even consider it at the moment.
Sorry for that last downer, but you couldn't really have picked a worse time. Depending on how many years of clinical experience you have, you might be better off going to business school, or perhaps spending a couple of years in pharma and then trying when things pick up again
Hope that helps
