re. age - I turned 25 halfway thru the year. There were a couple of folks in their 30s on my intake!
re. accommodation - You get used to it once you get into a routine. The apartments are fine! I actually loved living in Newport - you get to see that beautiful Manhattan view on a daily basis!
re. placements - I got a very good placement with Citi. It was challenging and I picked up a lot of new skills. The hours were 8.30-5.30. You get used to the schedule/intensity. Some people had better jobs than me, some people didn't - luck of the draw! I wouldn't look too much into it because working on a NY with a big company will look great on your cv and you will get out of it what you put into it.
re. location - 2 mins, completely safe. I should work for the Newport tourism board because I have nothing but positive things to say about that place. You live right next to a Target and a shopping mall with a cinema.
Anything I wish I knew? Not really, MB were transparent from the start. However, if I could turn back time to about 6 months before I started, I would have saved more money. I think you need to take around £3,000 - £5,000 spending money if you want to go travelling. I only took about £2,000. In June, I was on the breadline (I arrived in March).
My honest opinion is that this will be the most worthwhile thing you will do for your career.
