For securing admission in NL dalmia you need to ace the GDPI rounds after getting the calls. The chances to convert is moderate, if you've some extra curriculars and no gap years. The PI is usually grilling for MBA finance opting students. Youu'll be asked questions on current affairs, your opinions on these topics, if you read the news paper on the day of interview, the concepts from all what you've learned till now in CA, the articleship related questions and why you switched to MBA before completing your CA. Although as you're in final stage of CA, that can act as an advantage over other students. The graduation % is also decent enough.

You'll get the call for gdpi but prepare well for GDPI.

I hope this helps.
