Re: Comming back to Pakistan with 2+ UK experience in IT?
Amour, if you have hands on (design/development) experience in J2EE, you have good chances of getting a job in any reasonable IT house doing development in J2EE. You should not require any reference. You can apply either unsolicited or against some job posting advertised in any of the online job sites. If your experience is more of a management/consultancy, you may still apply for PM position but a reference will help.
I don't have a first hand experience about banks/telecom but I've heard that for senior level positions, they prefer candidates with references.
