Hello,
Technical skill does not mean mugging up physics, chemistry and maths. Even the people who do not have engineering degrees also possess technical skills, it means that the ability of a person to cope up with technology and the ability to handle it, nowadays even primary school kids have smartphones and they know their system better than adults, so this is their technical skill.
Yes, MBA will be a better option for you because management is a very versatile, lucrative and interesting field, but the most important thing is your interest and dedication, wherever you put your interest, dedication and will power combined.
If you have no interest in doing M.Tech then surely choose MBA but from a Tier 1 or Tier 2 institution, so that atleast you can enjoy the real benefits of MBA, and education quality in these institutions will be much better from those of others.
