There is no such difference between BE and B.Tech that makes one better than the other. Both are equivalent. Some colleges offer degrees with B.Tech written on them and some with BE. You just have to make sure you take admission in a good college.

Hi Sourbh, differs as per qualification and which country you want to work in. If you are planning to work in Germany, average salary is around the average pay for a mechanical Engineer is €40,000 per year. This might be less if for most fresher UG level jobs. Hope it helps.

According to my belief it comes under umbrella of Chemical engineering.
You may apply at HBTI(paint tech), IIT's or Lovely Professional university for related courses in chemical engineering and petroleum engineering.

MTech admission in good colleges is by GATE entrance examination. MTech is a very competitive exam. If your graduation education is not from a good college, your chances of getting a good college for MTech may not be high. Please reevaluate your startergy.
