Recruiter reached out on LinkedIn. I got an online accessment link.
Online Assement had 2 question which were both LC medium types. I can't recall the exact questions though.


OnSite Inteviews were scheduled


  1. Round1 : 2 LP principles and a question on FileFilter, filter files which are greater than 5MB and which have a .txt extension.
  2. Round 2: 2 LP principles and a question on Trie, to support basic operations like get, search, insert.
  3. Round 3: 2 LP principles followed by a DS question, I couldn't come up with an optimal solution, ended up doing the brute force solution. The question was that Amazon was running some promotions at different intervals and you have to find the maximum number of promotions running at any instant.
Example :- [[1, 3], [2, 5], [5, 9]] 
Output : 2
  1. Round 4: 2 LP principles and a quesion on URL shortener, clarified the requirements properly, came up with a good design and the hiring manager was satisified with the solution


Outcome : Rejected.
Feedback Received :- The recruiter told that there were some gaps in DSA apart from that everything was good.
