Hi puys
It's good to see my ex-company being discussed
I too took a few interviews there.. Apart form the inputs you already have - a couple of important things -
1. Be confident
2. Dont be overconfident
3. Dont say "ya... may be' to any question.. say a yes or a no
4. Its OK if you dont know the answer - dont panic
5. In case studies - dont give up - discuss
6. Dont forget to be confident
Hope this helps
I worked in BR for a year, took a couple of interviews too.
