As of now I am quite sure you dont have to give the technical exam in India .
That requirement has been there even on the earlier flow chart so its nothing new
However if your flying authority does not have technical specific ( like FAA ) ask your flying school to do the test and make sure you get atleast 70/100 or more .
This test has to be done prior to any flying training .

Yes if you give the skill checks in India the DGCA should issue you a Commercial single on the C172 . I dont think you should face any problems with that .
However be warned that if you dont have ME IR rating on your DGCA license none of the Airbus operators ( including IndiGo ) can hire you . You also wont be allowed to go for an A320 type and get it endorsed on your DGCA license. This is the reason why none of the Airbus operators cant hire you .
