      1. Given a sorted array of zeros and ones, find the number of zeros in the array.
      2. Given a sorted array of integers, find the number of times a given number K occurs in the array.
    • Your Approach:
      1. Initially, I explained the brute force approach (O(n) time complexity). When asked for optimization, I suggested using binary search (O(log n) time complexity) and explained the logic. I was then asked to code it, and after a bug was pointed out, I corrected it.
      2. For the second question, I used binary search on both sides of the array to count occurrences of K. The average time complexity was O(n).
    • Outcome: Cleared the round. The interviewer seemed satisfied with the solutions and corrections.

  • Round 2 - Technical Interview:

    • Questions Asked:
      1. Given a number n (number of open parentheses), find all possible valid patterns of pairs of parentheses (e.g., n=2: (()), ()).
      2. OS-related questions:
      • How does a process start?
      • Difference between a process and a program.
      • What does running a process mean?
      • What gets loaded into memory when a program is run?
      • From where and how is memory allocated during runtime?
      • What is a system call?
      1. Given a tree, find the shortest path between any two given nodes.
    • Your Approach:
      1. For the parentheses problem, I used backtracking to generate all valid patterns.
      2. Answered the OS questions based on my knowledge of processes, memory allocation, and system calls.
      3. For the tree problem, I found the nearest ancestor of the two nodes and calculated the heights from there. I optimized the solution by returning the height while finding the ancestor. I was asked to code, explain, and dry-run the solution, and I corrected a bug during the process.
    • Outcome: Cleared the round. The interviewer tested my understanding of DS and OS concepts and seemed satisfied with my problem-solving approach.

Preparation Tips:

  • Practice binary search and backtracking problems thoroughly.
  • Revise core OS concepts like processes, memory allocation, and system calls.
