There were 2 DSA rounds at first in which in the first one, questions related to binary search, linked list and LCS were asked. And the next round had two DSA questions related to binary search and trees. All were standard DSA problems (average difficulty if one thoroughly knows the concepts involved ).

For a 3rd year student intern, it was for a duration of only 2 months. In this, two rounds of DSA were supposed to happen. In the first round, I was asked 2 Medium level questions based on Trees and Matrix.
