Experience

Applied using LinkedIn, saw a posting there and applied

After Applying, I got a link to Hackerearth Online Assessment,
There were 3 Medium-Hard Questions

  1. Based on Dijsktra Shortest Path Algorithm
  2. Based on Tree Traversal
    Don't remember the third one

I completed the first one and partially completed the second one.

Got a call from Recruiter after few days, He told me there are going to be 2 rounds only ( one DSA and one HR)

Round 1 ( Problem Solving, 1 hour)

  1. Given a grid of m*n size, calculate the number of ways to move from top left corner to bottom right corner if you can only move in down and right direction. ( Simple DP question)
  2. Given a sorted array of negative and positive numbers, square all of them and give the output in sorted format
  • the brute force solution is to square all numbers and sort the array ( Complexity ==> nlogn ). They wanted more optimized solution.
  • I stored all the negative numbers and positive numbers in different arrays and squared them separatley, then merged those 2 sorted lists(since positive and negative number arrays are already sorted) (Complexity ==> O(n))
  • They wanted it to optimize it more to use constant space, I was able to give them the approach( binary search + two pointer) but there was no time to implement, they were fine with it.

Ex. input [-5, -3, 0, 1, 4 ] , Expected output [0, 1, 9, 16, 25]

Round 2 ( HR Round, 30 minutes)
Discussion based on my current company and projects.
Had to explain things in detail for my project.
Explain database systems used by Google sheets.

I was extended the offer a few days later.

Note: My first post, don't mind the decoration of the post that I have not done😂😂😂
