C'mon Rashmi - it's a bit lazy isn't it? Surely you can do a little research alongside your PhD into what you want to do with the rest of your life??But as you are on a consulting forum, I suggest .... how about seeing if a consultancy job is right for you? Depending on what your PhD is focused in a role in a bank could also be a good move. If you have really good Maths from a top university, something like strategy consultancy or risk management maybe (either Market Risk or further back in the food chain, maybe a a quant role designing models and stress tests)?
