Hello Anshul2504,
W.r.t. your remark "......this was once a racket in Bangalore"--FYI, this wasn't limited to B'lore. It was [and, to some extent, still is] prevalent in almost all the Metros of South, including Hyderabad.
You mentioned "I am not from 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 in CiteHR for any possibility of action. But since you preferred to post this in this Forum, looks like there are other aspects too. Pl elaborate.
Coming to the very specific individual about whom you refer to, where is he working now? If it's Qualcomm, pl mail me the details in-confidence [you can send a PM]. If not, where? We have access with 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 also, I am not really sure IF there could be anything that can be done in these companies--EXCEPT for a postmortem & the HR devising ways to tighten their Selection processes.
However, pl note that JUST the name & 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 [or any such] individual is surely called for.
Reg 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 also.
I also suggest that you SHOULD need to keep in-mind, as a 'Whistle blower', to be extra careful--on the personal angle. Hope you get the point. There's a clear reason why I am suggesting this.
Rgds,
TS
