Amazon arrived for hiring in the last week of Sept 2021 on our campus for the 6 months Software Development Engineer Role. We had a total of 3 rounds (1 Online Coding on Amazon’s Assessment Portal + 2 Technical Interviews).

Round 1: Online Assessment Round

The coding round comprised of 4 sections:

  • Debugging: We had to choose a language and debug up to 10 questions most probably. Codes were very basic like sorting, etc.
  • Coding: There were two medium-hard level questions.
  • Work-style Assessment
  • Aptitude: 25 aptitude questions (most probably)

Round 2: Technical Interview Round 1

Eg - 1 1 2 1 3 2  ->  -1 -1 1 -1 1 -1

Round 3: Technical Interview Round 2

  1. Clone a Binary tree having random pointers The structure of the node was already provided.
  2. Tell me about any technology that you have started learning or have worked on recently – Use the STAR method to explain. I was from ECE so I was also allowed to speak about any technology which may be related to ECE too.


  • Start from brute force and keep on optimizing when asked.
  • Speak while coding or thinking.
  • Repeat the question how you have understood it.
  • Keep track of edge cases.
  • Use STAR method for behavioral questions.

I guess they didn’t ask me any theory as I was from ECE and also not much time was left. Don’t take it for granted, it’s just an assumption of mine.

Verdict: Selected
