I got a mail from Amazon to apply for 2-months or 6-months internship. I applied for 2-month internship.

Question 2.

The problem involved utilizing dynamic programming to create successful combinations of 1s and 0s, while adhering to certain rules or patterns specified by a given data structure.

The problem was similar to https://www.geeksforgeeks.org/find-zeroes-to-be-flipped-so-that-number-of-consecutive-1s-is-maximized/

Round 2: Online Interview

The interview was scheduled after a week from the result date of OA.

Only 1 technical round of 1 hour was there.

The interviewer introduced himself then he asked me to introduce. Then he asked me 2 questions based upon my interest in Ethical Hacking. Since he also had some knowledge in the Cyber Security domain that’s why he asked me the questions mentioning it’s not a part of our interview.

Then he asked me 2 questions of DSA.

He opened a shared text editor to explain the approach and write the complete code including the main class.

Question 1.

The problem was to count the number of consecutive 1s in a circular array.
