Greetings gitansh!

Both the branches mathematics and computing and computer science engineering are best branches to be pursue. However there is more competition at computer science area as here you have opportunity to explore various tech department whereas in MAC, you have limited access to other facilities like machine learning. Some tech companies allow both branches to participate in interview but some restrict other branches like MAC to take participation. However many companies only allow MAC branches students to appear for interview.

The placement statistics in both branches are good,but it depends on your skills and area of interest that how much companies will offer you.However many people prefer CSE more compared to MAC as CSE students have benefit to sit in interview rounds.

Hope this will help you.
