Job dilemma again! Please help with any options or suggestions.

I've been looking for a core mechanical job since July this year. Sent a million applications, called another zillion but none of them have vacancies for Mechanical freshers. I couldn't even get an interview experience because there was none to attend.

So I thought of joining a BPO...till I get my core job. So I attended Dell Walk-in last week and got in for Technical Support. They asked me to join from 21st September (i.e., coming Monday). This company is hell strict about quitting without notice and completing probationary period. If I quit they will blacklist for ever for any position in Dell. So...if I join Dell, then I shall not think of any job in the period of 6-8 months.

I got a call today from a company called "First Security" which is a gulf based company and have started their operations in India (Hyderabad) 3 months back. They are into making airport baggage scanner, CCTV, metal detectors etc.,
My job is to have everything about baggage scanners right from maintenance to repair to everything about it on my finger tips at the end of the training which is 6 months.

If this company was in Bangalore, I would not be in such a dilemma...but this is in Hyderabad (which is in another state). I only spoke to my future team leader over the phone. He sounded very convincing and passionate about the job. I've no idea of the place, the company or even the people there. During the training I'll get a stipend of 5000 rupees. I've to stay in a PG...I've to take care of my stay, food and all the needs. And I dunno whether I've to go...for such small stipend and possibility of high learning.

I'm wondering whether to join Dell and do some course in the meantime..and start looking for job actively with better qualification after that

OR

Join First Security, learn to live away from my parents and gain experience in my core field..

Please Help!
