This is an unprofessional organisation with inhumane HR team. one of my known was selected by them as a campus hire but they did not release the offer letter instead made the candidate work for several days in return of promising the release of joining letter. Instead the HR mentally tortured the candidate and tried bullying with negative feedback. Few days back they again asked the candidate to contact them so that they can utilise the candidate for another few more days. I would suggest people to be aware of such people and do not entertain any bad behaviour from such organisation. Avoid them as much as possible
