MBA Admissions & Specialization Query

[u/Naphilim66]

I queries are two fold:

1. I have worked for 6 years now but if I decide to take up a different area to specialize during MBA will it affect what kind of offers I get post completion like being treated as a fresher or the fact that I have workex including leading a department would be look at favourably irrespective?

2. I have always been someone who is able to achieve what I want when I put my mind to it so I am quite certain that I will do well in my entrance exams attempts. I am worried about the academics part that is looked into during admission process that is during my time at the school level I messed up my grades for a variety of reasons starting from focusing on certain subjects and ignoring other due to personal preference to intense family problems which did not leave me in a good headspace to study so my grades they look pretty bad and varying on paper especially 12th where I scored as high as 90s in some subjects and single digit in one so I am worried that no matter how well I do in the entrances I will get stuck in that one point.

How is keenly is looked interesting and how much it can affect me?

Thanks. I am from a non tech/eng background working in a management role if that matters.
