I registered in various job portals for getting a job but was really very disappointed with their response. As all these portals are just money making sites. Also they have only BPO jobs to offer. I had got so much frustrated with this situation.
Finally I searched for an offline consultancy and got to know about wings aviation. They are spercialised in providing aviaition jobs. I registered there and given many interviews. So as per me it is usable consultancy.
