Articleship opening

Hi,

I am planning to take transfer from my current firm. Have given interview at few firms but didnt click. Tried at Manish Modi & Associates who is taking articles currently, but couldnt clear partner round. Also given at AP Nagpal, but no response. Manish Modi & Associates, gives good exposure is what i heard. wonder what went wrong in partner round. Pls help how to crack interview if i want to take transfer & if openings in other firms .
