Thanks for contacting Careers360...

Definitely you are eligible for a job but right now it will be not so high, Your salary will be around 10000 to 15000. 

I suggest you to continue your study first and join B.Tech.Some top universities of India like LPU, Sri Sai Ram Engineering College, Chennai, M.V.J. College of Engineering, Bangalore, Galgotias College of Engg. & Tech., Noida are providing B.Tech courses
