Summary

I had a positive phone screen for an SDE 2 role at Amazon. I was assessed on two Amazon Leadership Principles (Deep Dive and Ownership) and two coding problems: 'Subarray Sum Equals Zero' and 'Find K Pairs with Smallest Sums'. I performed well on the behavioral questions and the first coding problem, but missed a corner case on the second.

Full Experience

Hey guys,

Exp: ~6 YOE

I was asked 2 LP's - Deep Dive, Ownership I answered well.

Easy/Medium level questions.

  1. Range query based problem - return subarray that sums to 0 I gave working code
  2. Prority Queue based problem - given 2 sorted lists and integer k, return first k pairs with least/mininum sums, in increasing order. I gave closely working code but missed a corner case.

Verdict: Positive
