most of the friend i know under civil engineering ended up becoming IT programmer or other IT related job
reason?
environment issue
pollution issue
allergic issue
work life issue
time management issue
stress issue
money issue

if you have the passion and knowing your direction and what you wanna achieve....then go ahead and endures it
if you just go out there holding a paper and hope for the best...good luck, you might end up crying everyday looking for help to cope stress

i x know man, they just went it there and adapt those shit
when i heard about that switches, i am also wondering like you on how the heck they did it or even get those job at the first place
but believe me...they are still doing it up til today and its fully office based...hahaha
