I applied in july as well and was invited for an aptitude test which went well(thank God). was even sent a mail mid october informing successful candidates that the psychometrics assessment is coming up soon.
but there's the possibilty that the aptitude test is still being conducted for shortlisted candidates.your best bet is to call the HR unit. Pity i dont have their number but i'm sure you can find a contact number somewhere on their website..
