See this isn't a criteria for getting selected for cdac. Doing internships OR having job experience isn't must... Haan of course they do strengthen your CV and your personality and when they have to select one of the 3-4 candidates available whom they think of equal knowledge, then this factor might come into consideration ki yes ok this person has a job experience so I'll prefer him first. But that's not a condition. Understand the difference. Stay honest in the interviews. And if you are confident enough and technically knolwedge wise strong enough to impress them, there's nothing that can stop you from getting a job there. So be prepared, and give your best.

Best wishes. Thank-you.
