You have already done your BTech and trying for a technical job.
Please try to find out what is your aptitude and what is exactly meant by a technical job. Only reparing machineries or designing new technical items or operating scientific equipment etc is not a technical job. There is a wrong concept that until unless someone is not directly involved with scientific or technical machineries or equipment it is not a technical job.
If you exactly pin point your aptitude then only you will be able to search a suiting one.
If you have aptitude for teaching line you can very well try that and if not in Govt sector you can search in private one. If you are much inclined for operating machineries and equipment you have to search in manufacturing or maintenance companies.
On the other hand if you have interest in computer networking or software side you can increase your knowledge by completing a suitable course or diploma in web designing, data base, ERP related course, animation etc.
These are some avenues where you can concentrate.
No job is small or big. It is only the opportunity which will land you a good job. Even a small job is good for experience gain. You can increase your computer expertise by offering your know-how to your small organisation.
Stick to a job for some time otherwise you will lose the experience which comes with it.
If a job has enlarge elements of work that is multifarious activities take it and do not bother for salary.
Please remember that until unless we increase our skills it will difficult to do a job successfully.
Thoughts exchanged is knowledge gained.
