Thanks for A2A

Brother with my 2 years of academia at NIT makes me eligible to answer this question.

Your 90% of placement revolves around how well you have performed at college. Very few factors like an excellent rank in JEE advanced or qualifying an olympiad can bring impact and that too would be in very few companies (like those having JEE coaching domain). 

So, from the above sayings their is hardly any impact your X11 scorecard would bring in your placements interview.
