Hi Abid
Wish you luck with your job search in India. Its a good thought of returning home. Seniors have advised very well how you can go about it. My suggestion are :
Target which Industry amongst IT you want to explore, dont be desperate for any job which pays you well.
Research what kind of skill sets are in demand and whether you have them, if not seek to acquire them.
Draft a robust CV highlighting your work experience and your future aspirations. Arrange and scan your documents, keep them in your email for ready access. Keep your testimonials and reference ready, preferably in India.
Draft an interesting cover mail presenting your cause, be honest, express your passion towards returning to India, dont crib or whine about UAE or Current Employer.
Research list of companies which meet your criteria (location, size of the company, nature, etc)
Streamline your approach towards companies, how you want to apply (Email, Job Posting, Telephone call, Fax etc), if possible use your contacts in India, Get HR's, Hiring Manager's, Senior Employee's contact numbers and forward your application. Dont get too pushy, be smart and patient.
Network smartly on professional websites, make relevant friends, be genuine dont be shrewd.
Plan your vacations to India properly (Avoid Monsoons), shortlist companies you want to visit as walk in application. Network, Coordinate, Communicate with relevant people from targeted companies and strike a meeting, official or informal.
Prepare your mindset for salary negotiations, set your priorities right (India, Salary or Job Profile) you cant get everything in one plate.
Prepare mentally for change in Lifestyle, Inflation, Work Load, Office Politics etc. "Grass looks greener on the other side"
Your growth is in your hands, take self initiative to acquire skills and qualifications. Dont get stagnant, as you are in technology field.
You can use Various Sources to Apply and Keep track of your application, prefer to get real human contact when you apply, as compared to bulk forwarding your CV.
Research Top Consultants : Adecco, Mafoi, Manpower, Kelly etc.
Wish you all the Best
