thats good u r not leaving ur current job. well what ur friend has told u that is right in some way bcz here companies usually don't hire for sensitive jobs without taking test and interviews, regarding dropping of ur cv, select some companies which u or ur friend think of worth trying, and about giving an ad in newspaper i m clueless coz it might help or might not help,,,but in my opinion it is not cheap bcz sometimes companies need the skills u have so why not to give it a try. my point is u should use the every possible way,,,if u succeed in finding a job here it would be worth trying and God forbids if u don't get it even then there is no loss other than some financial crunch for a while.ur job would be safe back there. Make a budget before u come here, list down all the possible expenses based on ur expected period of stay and in case of failure how much time u would need for financial stability again. if ur circumstances allow u to take such financial risk then it is fine otherwise be wise and spend carefully. after all u are a better judge of ur situation there. Be clear on all point before u decide.
