im in c.s.
32 yrs old. been in min for 4+ yrs.
6k+ per month gross.
1st class hon w masters from ivy league. non-scholar.

Agree that ur fren is likely to have overstated his salary. either that or included his bonus into the calc.
I guess whether u shld jump depends on why.
if money, dun bother, cos the skills aren't so transferable.
if work-life balance, its aint exactly 9-5 in c.s. i typically go home at 7. but half the time, I have to log on from home and during the weekends...
