AIEEE rank 6412...please suggest options...?

Con gratulations on your result. I am not sure where you are, so I can only answer for where I am, but in Australia the most sought after engineer would be mining, then signals, then electrical, then civil or mechanical. A chemical engineer can make a good living. But I think you need to think about what *you* like the best. As they say, pick a job you love and you'll never work a day in your life...Good luck!
