Hello Anshul2504,
Regarding your remark "......this was once a racket in Bangalore"—FYI, this wasn't limited to Bangalore. It was [and, to some extent, still is] prevalent in almost all the Metros of the South, including Hyderabad.
You mentioned "I am not from the HR department (but I am part of an organization where many such fake candidates lurk around)"—have you reported the matter to your HR then? That could have been much easier than posting this issue on CiteHR for any possibility of action. But since you preferred to post this in this forum, it looks like there are other aspects too. Please elaborate.
Regarding the very specific individual you refer to, where is he working now? If it's Qualcomm, please email me the details in confidence [you can send a PM]. If not, where? We have access to many IT companies, and if I am convinced with the material you say you have, we can give it a shot with the companies.
Even though you mentioned that he earlier worked in L&T or Anite Technology as well, I am not really sure if there could be anything that can be done in these companies—except for a postmortem and the HR devising ways to tighten their selection processes.
However, please note that just the name and designation wouldn't help to ensure some action. You will also need to provide specific evidence of faking—at least to the extent that convinces any HR that a serious revisit of the entire hiring process of this individual (or any such individual) is surely called for.
Regarding Saswatabanerjee's suggestion to approach NASSCOM, I am not really sure if it will work. To the extent I know, NASSCOM takes inputs/complaints from HRs of IT companies officially, for a few valid reasons. But I am not sure if they have a system to entertain complaints/info from individuals as well.
I also suggest that you should keep in mind, as a 'whistleblower,' to be extra careful—on the personal angle. I hope you get the point. There's a clear reason why I am suggesting this.
Regards,
TS
