how can I get a high salary job after chemical engineering?
After completing your B.Tech, you need to apply for jobs. If the college provides placement facilities, then you can appear for that. Otherwise, you need to search jobs off-campus. Some top companies which hire Chemical Engineers are ITC, HUL, Schlumberger, Reliance Industries, GloxoSmithKline, L&T Etc. Many PSUs also recruit chemical engineers like SAIL, GAIL, ONGC, Indian Oil Corporation etc.
