I utilized for the Amazon WOW SDE internship in June 2022. (for 2023 passports) There was a complete of two on-line coding rounds, and 1 technical interview.
On-line Spherical 1: (July 2022): Platform: Mettl. It was 90 minutes – 40 MCQs (5 questions from every matter – OS, DBMS, pseudo code, Linux, Software program engineering, Software program Testing,..) and 1 coding query.
On-line Spherical 2: (August 2022): Platform: Hackerrank
I acquired mail that I’ve cleared the primary on-line spherical and the following step is to register on the Amazon jobs web site. Then hyperlink to 2nd on-line spherical will likely be given there. This spherical has 2 coding questions for 45 minutes.
Technical Interview: (September 2022.)
- There was just one spherical and I attended it within the Amazon workplace.
- The interview lasted for round 1 hour and I want to unravel 2 coding questions.
1st coding query: (on strings)

- First I instructed the brute power method after which the interviewer requested me to optimize it.
- I gave him the answer utilizing stack, and I used to be requested to jot down the code on paper.
- Then for the second query, he requested me whether or not I’m comfy with Bushes. I mentioned YES, however I used to be truly not.
- He gave me the query: https://www.geeksforgeeks.org/find-duplicate-subtrees/
I couldn’t remedy it, so he modified the query.
2nd coding query: Then he modified the query to Discover the variety of permutations of a given sample in a given string.
My method was:
- Retailer the frequency of every character within the sample on a map.
- Traverse the string, just like the sliding window approach, and retailer the frequency of every substring of the sample’s size.
- Evaluate the frequencies and if it matches, improve the rely of outcomes.
- Replace the frequency of the substring for each window.
The interviewer was fairly impressed with my answer and I used to be requested to jot down the code for it. We had a small dialogue on my initiatives and likewise his expertise at Amazon.
End result: SELECTED (Received mail after every week)
Suggestions:
- The one factor issues for this interview is coding questions, nothing else.
- Don’t attempt to think about one of the best method, at first, simply inform out loud no matter method you get.
- Inform them in case you are caught and they’ll make it easier to.
- Suppose earlier than you say that you’re assured in any matter.
- Vital: Undergo GFG interview experiences as many as doable. It will make it easier to very a lot for any firm interview.
