Understanding the Junior Trader role at FT

Hello! I'm applying for the position of the Junior Trader at Flow Traders. Can someone please shed light on the working hours and the kind of stress I would be exposed to in that role? Also, if possible, granular details like
1. when do people usually wake up
2. what time are they supposed to reach the office and at what time do they usually go back home
3. What are the usual skill gaps among those people who can't make it past the training period?
4. What skills and concepts will I learn as a trader? Will I get exposure to concepts in statistics, computer science, math, combinatorics? Or is the job of a trader confined to quoting sell and buy prices only?
5. How is life outside of work as a trader, in amsterdam? in NY?
6. What are the exit opportunities after a trading experience of a year or two? From whatever I could research, the exit opportunities aren't that great. Is that true? One of my friends told me how a lot of traders go back to doing a math related PhD or end up in a hedge fund. Comments?
7. Is access to better exit opportunities a good reason to apply to NY instead of the Amsterdam office? I read somewhere that FT's NY office sucks.
8. If I choose to work for 3-4 years as a trader in that firm, will I get enough managerial opportunities in the company that'll allow me to write a good application for an MBA in Wharton or similar schools ?

Thanks a ton in advance!
