Amazon Intern interview questions

Amazon came to our university for taking interns. There were few online mcq+coding round and then few face to face interviews where coding questions were asked. Mcqs asked were from oop,c/c++,data structures and algorithms. Questions asked were from easy to moderate difficulties. 1 particular question was tough. That was the bar-raiser. I managed to solve that one and got selected.

Amazon came for the campus recruitment for Internships. There were total of 3 rounds for the process. In first round there were 2 programming questions and 20 technical MCQ. Second round was pen and paper. Third round was technical interview
