I applied via Campus Placement and was interviewed in May 2023. There were 4 interview rounds.
The aptitude round consists of quantitative, technical questions mainly from java ,oops, ds concepts , some from os . Negative marking was there with 0.25 mark deduction.
It consists of three coding questions and that was pretty much easy . 1st qn is easy and so is the 2nd question . Third question is kind of medium level (but not so tough ) . It was a question related to doubly linked list . 1st and 2nd were array and string questions. We had this in pen and paper format , not in ids .
