After clearing L1 interview at LTIMindtree how many days it takes to schedule L2 round ?

Hi in the last Saturday (24th May) I appeared for a Walkin at LTIMindtree office at Kolkata. They told me after clearing the first round that you are done for the day but L2 will be happening for me they will let me know. Do you know how much time it takes to schedule the 2nd round interview?
