This was on-campus Amazon OA test for Amazon India (July 2021)
FT/Intern

Each section had there own time.

There are five parts to the test.
1)Debugging
2)Coding
3)Aptitude
4)Personality Questions
5)Feedback Survey

Debugging(20 min)
It had 7 Questions. That I had to correct small mistakes in the code. It was pretty easy. A 2nd year undergrad can do this section in 10 min.

Coding(70 min)
It had two questions. I would rate them medium/hard.
First Question was a little variation of Maximize units Truck Value.
https://leetcode.com/problems/maximum-units-on-a-truck/

Second Question - Here entry times and directions where given for customer , and return array for persons time when he pass by turnstile.

It was little variation of this Question

Compiler was pretty messed up. I wasted lot of time figuring out an error.

APTITUDE (35 min)
It had 24 Questions. You cannot go back or forward in questions. It had coding decoding and statement conclusion questions mostly. Some series based questions and paragraph based deduction questions.

Personality based questions(No timer)
It wasn't numbered but I guess it had 20-30 questions. Each question had slider which was kept at between at start we had move either way which we think is most appropriate according to us.

Both sides has different view points and two options most likely and more likely.

View Point 1 ............................................................................................ View Point 2
<-----Most Likely--------More Likely----O-----More Likely-----------Most Likely------->

I had 4 options and 1 choice to make which most correct according to us.

Feedback Survey(No timer)
This was just feedback about the test. But it was part of assesment without it you wont be evaluated. It question regarding assesment platform like was it frustrating , did you understand the work at amazon by assesment, how likely you reccommend others to apply at amazon etc.

Five options - strong disagree, disagree,neutral,agree, strong agree
And at last a textbox where you can write your feedback in words.

I hope it helps you. Thank you
