The interviewer asked me to reverse a link list and asked many other questions as well. The questions were quite hard and required a thorough knowledge of data structure and algo.

first phone screen using online coding and then Virtual on site using google meet. virtual onsite was difficult , specially difficult to explain without white board. There were 5 round of interviews on same day . one round is HR/ethic question and 4 round technical coding.
