There are two aspects to your placements, whether you are concerned just about the immediate packages or if you are concerned about the long-term career prospects.
As far as only the packages are concerned, CGPA matters only in some of Companies. To stay on the safe side, try scoring between 6.5–7.0. The reason CGPA is considered for shortlisting is because of the huge batch size. Usually, students scoring less than 8.5 don’t clear these interviews. Apart from CGPA, you will have to convince the recruiter that you are a suitable candidate for the job through your communication skills and knowledge.
For your career prospects, CGPA alone is never enough. For some the placement drives are excellent opportunities while for some they are horror. However, when your career is concerned placements are not the only thing that can help you. So it’s better to not get overwhelmed. I know someone who failed to get placed in KIIT and ended up with the highest package in off-campus placements. If you want a bright career, try focusing on your passion rather than placements. Do something you absolutely love and success will find you one day.
