The 2nd coding question I got was like: ``` For example, given "2345", possible outputs include "335555" or 234 instances of the digit 5. ``` **My approach:** 1. I analyzed the possible combinations. 2. Then I implemented a recursive function.
During the first phone interview, I had to go through my project and complete a coding question which was the original LeetCode 373. I had to write tests and run the code. The interviewer was very nice, and I passed this round. In the second round, I was asked...
My onsite interview consisted of five rounds. The first round was a behavioral round. The second round involved designing a KV store with a senior engineer. The third round was a deep dive into my past projects with the hiring manager. In the fourth round, I h...
The interview process consisted of four rounds: **Round 1:** Quadtree is a tree data structure in which each internal node either is a leaf node or has exactly 4 children. Quadtrees are most often used to partition a two-dimensional space by recursively subdiv...
I encountered three questions in total. **Part 1: Coding** I was given a DNA string `dna` and was asked to calculate the cost of converting all its substrings into palindromes. The cost is the number of character modifications needed. The final result should b...
