AMAZON LOOP INTERVIEW SDE -1 ROUND-1:DOUBT REGARDING RESCHEDULING
Summary
My Amazon SDE-1 loop interview had a rocky start with a rescheduling issue, but I successfully completed the first round, tackling the Minimum Coin Change problem and some leadership questions, and I'm now awaiting further communication.
Full Experience
I completed my Online Assessment (OA) for Amazon on January 17, 2025. On January 22, I received an email notifying me of my scheduled Loop interview for January 23. However, during the scheduled time, only the shadow interviewer was present, and the main interviewer did not join. The shadow interviewer informed me that my interview would be rescheduled. For several days, I didn't receive any follow-up communication, which left me wondering if I should take any action or if it was a missed opportunity.
Fortunately, I finally received an email for my rescheduled interview on January 27, and my first round happened on January 29. In this round, the interviewer asked me about the Minimum Coin Change problem. I spent about 50 minutes explaining my approach, starting from a recursive solution and progressively moving to a space-optimized dynamic programming solution. After the coding problem, I was asked two leadership-related questions. I feel I performed well enough during the round, but I'm currently waiting to hear if I will be invited for Round 2.
