Hello paidikalayesukrishna,

Well, NIT Calicut has total 96 students placed out of 107 registered students, and with Highest of 38 LPA pakage and average of 11.94 .

While in NIT Rourkela,

So, For ECE, NIT Calicut has a better reputation than NIT Rourkela, And No Doubt ! both are good for ECE, but as per your demand, NIT Calicut will be my recommendation...

for your reference , NIT Rourkela, Placements (https://www.nitrkl.ac.in/Placement/Placement-Statistics/Placement-Statistics.aspx?jfhjf=2019-20) and NIT Calicut, Placement (http://www.nitc.ac.in/app/webroot/img/upload/2019-20PlacementDetailsFINAL.pdf) ...

(NOTE: All the data is of 2019-20, and based on statistics and approximation)

Hope this helps, and feel free to ask any further query...
