Google Interview Experience for Software Engineer (November 2020)Note: All rounds were virtual.Phone Screen Round:Implement a doubly-linked list, with all edge cases considered.Onsite Rounds:Round 1: Add (Key, value) pairs of two lists which are representing different values at different time stamps. HINT: USE Interpolation and Extrapolation, to find the values of the missing time stamp.Round 2: The question […]
