They will ask some basic computer knowledge questions, including two programming problems with a difficulty level roughly equivalent to medium-level problems on LeetCode, such as the "Big Integer Addition" problem.
Interview questions [1]
Question 1
Implement a function addStrings that takes two string inputs representing large numbers and returns their sum as a string. The challenge lies in performing the addition operation manually since standard integer types may not support such large values. This involves simulating the addition process digit by digit from right to left, taking care of carrying over when the sum of two digits exceeds 9.
