Narula Institute of Technology will be a better option for you. Both have decent placements. In Academy of Technology the major IT recruiter is TCS and students also get a chance to sit for pool campusing conducted by various companies like Tech Mahindra. In Narula Institute of Technology they have at least 70-80 % placements and companies like TCS, Cognizant, Capgemini and others visit.

So both will be good but Narula is a little better since you can have many alumni placed with different companies. The rest is your decision.

All the very best
