Dear Arnab,

It is recommended that you should prefer a branch based on your skills and interest.

There is always a good scope for a right candidate who have desired skills and knowledge. 

If we compare the scope of chemical engineering with other branches like CSE it has less scope in terms of jobs and placements.

You will get a good placement if you are pass out from top colleges. 

If you are interested in this field make sure you take admission in top colleges which provides good teaching and placements.

You can check the top colleges for chemical engineering below

Good Luck!!
