Actually... This can be also seen from another perspective.
The IT field is not as volatile as others, and thus fewer jobs
are posted in the classifieds.
Moreover, this field and its not very big. There are also
quite a few job agencies that are specialised in only sourcing for
IT jobs.
These companies don't frequently post ads on classifieds
(costly) and after awhile, these job agencies have (roughly 80-90%)
of all job resumes in the market anyways.
While you're new in the job market, its easy to come to the
conclusion that theres this awesome job waiting for you to do and
paying you something you're happy with.
However, once you hit say, 30-40 yrs old, and you've been
working 10-20 yrs, you would be more astute and your perspective
would tend more toward the "Hmm, so this job has high turnover"
kind of perspective.
Its always good to gently inquire the nature of a job opening if
you can sneak it in the interview. (high turnover/company
expanding/excessive workload, all possible considerations)
# My humble opinion is just stick to what you enjoy doing.
You'll likely do it better or wont get burnt out so fast as people
who make a financial decision when picking their career. (Those
people who do, might leave and give the passionate ones a
chance!)
# Every industry will be filled with people who do it for
passion and people who do it for other reasons. Try to learn from
everyone but feed off the energy and enthusiasm of more passionate
colleagues (^.^)
I'm a passion junkie.
