I am 7 years of exp in data networking domain(wiith some relevant certifications) and here in London for last 5 weeks .
For all these 5 weeks i am just able to attend 1 interview and that too when i went to attend interview there was mismatch in my profile and job description.
I am seeing some relevant job openings but somehow not able to arrange interviews.I am getting calls from consultants and most of the times never comes back ,sometime they are asking for Security Clearance, UK exp and sometime get mail from consultant that unfortunately i am not successful to proceed further due to high volume of applicants.Ultimately not able to arrange interview itself leave further step.
Initially i thought to here for 3 months but the way it is going i think i have to return back in 2 months as i am not getting interview calls also.

Any suggestion is welcome thanks very very much in advance.
Thanks,
Manu
