If you join NIIT you will not get knowledge, instead you will learn how to commit FRAUD and SCAM in broad daylight.
1) They hire beggars from the street as faculty. In future they might even hire monkeys as faculty. Even a monkey will have more knowledge than the NIIT faculty.
2) You will not gain any knowledge! This is a proven fact.
3) They will delay your course. If your course should be complete by 6 months, they will only complete your course only after 1 or 2 years.
4) They will make sure to collect the course fee very promptly. They DO NOT give refunds, it is their strict policy. If you ask refund they will say that you have ask refund within 7 days after paying fees. But they start the course classes after the first 7 days of paying fee. Only after attending the classes you will realize that NIIT is a scam, so now when you go to ask for refund they will say you should have asked within the first 7 days of paying fee.
In short it is impossible to get a refund from them.
5) Students are treated like beggars.
6) They say 100% you will be placed in a reputed company. But my batch mates at NIIT are now working at a call center.
Overall it is a complete fraud company.
