I recently had the opportunity to participate in Amazon HackOn, where my team successfully qualified for the second round. Unfortunately, we couldn’t make it past that stage. However, two months later, I received an exciting email from Amazon inviting me to apply for a 6-month internship. After filling out the form, I received an Online Assessment (OA) link. Following the OA, I was selected for the interview process. During the interview, I was asked two DSA questions, which I would classify as easy to medium difficulty.

The first question involved a binary matrix sorted in decreasing order, where I had to determine the row with the least number of 1’s. The second was based on strings: given two strings 'a' and 'b' containing alphabets and the character '#' (which acts as a backspace), I had to determine whether the two strings were equal after processing the backspaces.

Overall, it was a great experience, and I learned a lot throughout the process.
