Dear Dinesh,
If "lot" of employees with "fake" experience find a place in MNC, then it could be recruitment malpractice. But then do you have a firm evidence of malpractice in recruitment? If this is true then it must have happened with the connivance of HR. I doubt, whether writing to HR will work in anyway. However, make sure that you are not playing with anyone's career.
For Dfc9fc9a5a2add958475eb16e: - The originator of the post could be "social watchdog". Therefore, caution him however, I would not recommend you muzzling his voice or discouraging him. After all company none less than Yahoo had appointed CEO who had fudged his CV.
Later he was sacked <link updated to site home> ( Search On Cite | Search On Google ) is altogether a different matter. These things happen inadvertently as well. It may or may not be a scam. Those who get employment by deceit do injustice to those who stand for values and do not adopt deceitful means to get employment. You have not written directly but then your post implies one should be mute spectator to anyone's wrongdoing however, this very tendency has put our country in dire mess!
