dear studnet

If you are quite deeply interested in chemical engineering subjects you can do M.Tech. and then Phd. after which you can do a job in research sector of a company.

give GATE and get admission in NIT/IIT/IISc.You can also get into PSUs 

if you are interested in managerial role do an MBA and boost your career. Go through CAT and get admission in IIM/IIT/NIT/IISc.

hope this helps

All the best!!!
