Amazon Software Development Engineer interview questions

I applied for the internships in summer,after one week, I receive the email,showing that I should take an OA in one week, in the OA, there are about 10 question need to be finished in 30 minutes, there are some simple coding questions such as make a for loop to print a certain graph, and find some bugs in a certain code. after OA, if you pass, you will get another email to make a appointment for a phone interview.

The company visited my college campus for internship . Had a coding+aptitude round . Therafter shortlisted candidates had 2 personal interviews . In the end 10 interns were selected . The selection process was quite good , the questions asked were good enough to filter the candidates
