Off late - I have received several calls from so called Premium Recruitment Service Recruitment agencies operation for India, Hyderabad/Bengaluru and Chennai.
Thy claim they have a requirement which exactly matches your profile. Then they pretend to confirm you profile - which normally is openly available on Linked in or other job sites where you may have posted it.
Then they will tell you about the salary offer - which is very lucrative and they can guarantee you that they can get you the job.
Now next dialogues are most important - they will inform you that these jobs are not advertised and they will position you through internal contacts . but they need a small service fees - 1000 USD or some such amount which you need to pay before they arrange your interview.!
Any reputed organisations who need you will pay for your recruitment rather than asking you to pay.
