What is the companyies eligibility criteria less than 58%
I got 78% in 10th and 50% in 12th and less 58% in engineering but in the engineering year 3 years gap that's why I ask you which companies I am appear
Most of the companies especially MNCs that I know of require 60% at least. Your best bet is to find out SMEs / startups that recruit candidates on the basis of their skills.
My recommendation is to build a solid skills-set and acquire certifications; and approach smaller companies directly. That should get you a big boost.
