you will download data into spreadsheet and run those macros to generate some reports or some data required by trading desk for their decision making.
Everyday you will be doing the same thing.
If you wanna jump from this position to front Office, of coz possible. Anything is possible because all kinds jobs I ever see some cases that ppl directly go into trading biz . like Computing, Engineering, even arts and social science.
It all depends on your own personal quality and LUCK, sorry , have to say this. I know millions of ppl is dreaming the same dream, so you must make yourself different to let the employer hire you and you need to be good at networking. know more traders. know them well. let them know you well also. so that when they know the positions, they can think of you.
anyway, this is just a good offer, if the salary not bad, go for it. the subsequent jump all depends on what you are doing in your job and out of your job.
