B.Tech

Hello dear, The faculty is also average. Graphic Era, Dehradun is average, though its a government. University. Of all two, Chandigarh University looks a better choice. Some more information regarding Chandigarh University:
Ya one of them got a package of 24 Lacs but only 1 of them and that too last year. See Chandigarh university is an emerging university. I won't say that its bad but its not one of those prosperous ones but we cannot tell the taste of a sweet without tasting it (paradox but still). Recently they have placed around 1000 students on a single day at Accenture but at a minimal package. So think and think before you proceed.

Not so good.
Even though the Training and Placement department of NITT shows above 95% placement rate,it is only after going through an initial screening process called CPC'S conducted by immediate seniors of the same branch.Only about 40 out of a current batch of 60 are eligible to sit for placements after successfully passing the CPC process.From these 40 only 12-15 people get placed in core Metallurgy companies like Tata Steel,TVS,Tata Motors,Reliance etc.The rest opt for Management companies(generally Analyst roles) like KPMG,PWC etc and some other companies like Amazon, Flipkart.
The packages offered for core companies isn't that good and is around 9 for Tata Steel and others average 6 LPA.Management Firms offer a better initial pay of above 9 and hence the trend.Despite all these some of them go for higher studies,some take care of their own business and some startup few companies.
Bottom Line
If you are looking into this field as a prospective career option due to passion/interest well and good.But if its just for a good initial pay,not so much.
