Amazon Advertising Software Engineer Interview Experience: confidence intervals alongside DSA

After resume shortlisting, I completed an OA and two virtual interview rounds. The process focused on DSA, gen-AI discussion, and my projects. The DSA work leaned toward arrays, stacks, and subsequence-style problems, with behavioral questions mixed into the sessions.

One tightly timed part had probability and statistics estimation questions. I had to give the answers and say how confident I was in them, including a few confidence intervals. That made it about judgment under uncertainty as well as algorithms.

The difficulty felt average, and the process was coherent about assessing more than coding. I did not get an offer.

Location: Bengaluru. Overall feedback: positive. Offer status: no offer.
