PayU Interview Experience | 2+ Years Experienced

  • Last Updated : 30 Jun, 2021

 I received an email from a recruiter to schedule the virtual interviews. The recruiter informed me that each round would be an elimination round, meaning that if I did not perform well, they would not proceed to the next round. Three rounds were planned in total. [2 technical + 1 (Technical + Managerial)].

All the rounds were on the same day. 

Round 1: An SDE-2 intercepted it. His communication and technical abilities were excellent.

  • Depth Sum or Nested List Weight Sum 
    Sample Input: [1 [4 [6]]] Output: 27.   
    Explanation: 1 * 1 + 4 * 2 + 6 * 3 = 27( Number in the red color are the level in the nested list. )
  • Derive time and space complexity for both the problems
