Interview Process

The interview consisted of a 45-minute Zoom session following an online assessment. The candidate was required to share their screen and complete the coding tasks on CoderPad.

Technical Questions

  1. Add Two Numbers
    • Topic: Linked List, Math, Algorithm Design
    • Description: Given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return a new linked list. You may assume the two numbers do not contain any leading zero, except the number 0 itself.
    • Example:
      Input: (2 → 4 → 3) + (5 → 6 → 4)
      Output: 7 → 0 → 8
      Explanation: 342 + 465 = 807
    • Constraints:
      • The number of nodes in each linked list is in the range [1, 100].
      • Each node contains a single digit [0, 9].

Tips & Insights

It is advisable to practice common algorithm problems, particularly those that are frequently asked in interviews, such as those found in the top 50 lists for the company.
