Amazon Interview Experience for SDE

Online Round: There were multiple sets. Each set contained four sections.

• Code Debugging section(20 minutes)-It demanded only 10-15 minutes and only minor changes were required for correctness.
• Coding section(70 minutes)- Two coding questions were asked. I do not remember exactly what were those but the first
  one was very easy and the second was a medium-level question. The second question was based on two
  pointers approach as well as it required a bit of greedy thinking. I was able to complete this
  section in 40 minutes.
• Work Style Assessment(20 minutes)-These consisted of behavior-related questions in which you have to select the most likely
  an option that portrayed your qualities.
• Logical Ability(35 minutes)- These consisted of MCQs which tested your logical reasoning. You can prepare them from here. Speed matters so don’t waste much time on a single question.

Around 42 students were shortlisted for interviews.

Interview: It consisted of only one round which was purely technical. I was asked 2 coding questions:

• https://www.techiedelight.com/change-elements-row-column-j-matrix-0-cell-j-value-0/- Time complexity and space complexity mattered strictly. No extra space was allowed. I was asked to write code for it which I wrote correctly so we moved on to the next question.
• https://www.geeksforgeeks.org/next-greater-element/ – Again Time complexity and space complexity mattered strictly. O(N) space and time complexity were required. I also did this after this technical part ended.

Then the Interviewer asked if I had any questions for him in reply to which I asked the type of work that interns are emphasized on. Then the round ended.

Tips:

• Be confident and speak loud and clear.
• If you do not understand something ask them before moving on.
• Use proper variables while writing code.
• Write short and clean code so that it is easy for you to explain to the interviewer.

Results:

Finally 22 students were offered internships for the SDE profile.

Verdict: Selected
