Amazon | Phone Screen | 100 Closest Points 3D

Position: Web Services SWE Winter Internship
Result: Rejection

OA1:

  • Debugging and Logic Puzzles. Mostly Strings and Arrays for debugging. Simple fixes. Logic Puzzles I didn't know much but I was able to get OA2.

OA2:

  • Given a 2D sorted matrix find the given value.
  • Question Two: I had no clue how to do it. But I somehow got to the next phone screen.

Technical Phone Screen:

  • First 30 minutes, questions about leadership principles and projects that I've worked on on my resume. One question was: What is one project you've worked on where you had to deliver under time constraints? What is one setback you had on a project?
  • You're given a billion stars and their points in (x,y,z) in the sky. Return the 100 closest points. I used distance formula for each point and then I put it into a maxHeap of size 100. I thought I did it correctly but I got a rejection a few days later.
