I work in the midlands for a large ISP, done nothing but Cisco for 10 years and now look after some of the UK's biggest customer's solutions...
My work history:
1.> Part time at a college doing basic server and network support, having blagged my way in, - minimum wage.
2.> Passed CCNA, went to a large Cisco gold partner, £30k a year, was only 20 at the time.
3.> Moved to a security company working mainly on checkpoint firewalls, took a bit of a paycut for simplicities sake and the fact the place was less than half a mile from my house, £26k a year.
4.> Went to work for a large university and did all manner of stuff there, ended up on around £35k a year, now age 24
5.> ended up at a large ISP in the midlands doing complex design and installing large projects, ended up on around £45k a yearish
6.> Still in the same company, 27 years old but looking after Business customers at the highest level take home around £65k, thinking about changing at the moment although unsure where to go.
If I had any advice to someone wanting to start out in I.T - just get a job, work your ass off, learn everything you can and use it, build an awesome CV and sell yourself. But you have to eat/sleep/drink it for the first few years, you can't blag technical ability like you can sales or management jobs.
