If you are sure about getting into corporate practice then don't waste time. Do a 5 year course and start working. Recruiter are little biased towards 5 years students especially from T1 and T2 NLUs. So its better to do 5 years from a good college (T1 and T2 NLUs, Symbiosis, Jindal) and also at the end of the day comes down to hard word, and discipline with a little bit of luck.
All the best!
