Advice on ISB Round 2 applications

Hi folks,

I had applied for ISB in Round 2 last year with a score of 640. Got an interview call which I could not convert. Wanted to evaluate my chances for this year as I plan to reapply in Round 2 this year:

GMAT Reattempt 1: 660 Q49, V31, IR7, AWA 5
GMAT Reattempt 2: 660 Q50, V29, IR6, AWA (awaited)

Profile: B.E. from BITS Pilani, Rajasthan, 7.17 CGPA. Work-ex: Novartis, currently working as Brand Insights Manager (total work-ex 6,5 years), international professional work-ex in Europe and US (spent 25% of time).

What are my realistic chances ?

Also, if I go ahead with my application, which score I should go ahead with ?

Appreciate your inputs.
