Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.

  • Q1. Reverse a linked list.
  • Q2. Merge sort on a array/
  • Ans. 

    Merge sort is a divide-and-conquer algorithm that sorts an array by recursively splitting and merging sorted subarrays.

    • 1. Divide the array into two halves until each subarray contains a single element. Example: [38, 27, 43, 3, 9, 82, 10] becomes [38, 27, 43] and [3, 9, 82, 10].

    • 2. Recursively sort each half. Example: [38, 27, 43] becomes [27, 38, 43] and [3, 9, 82, 10] becomes [3, 9, 10, 82].

Interview Preparation Tips

Interview preparation tips for other job seekers - I prepared mainly from geeksforgeeks. I believe gfg is sufficient for prepration for tech interview rounds. There were a total of two technical rounds and one hr round. Before this there was an online test too where they had moderate level questions from data structures and tough questions on operating system . In the first technical round they asked me basic coding questions on techniques like hashing,bitwise operators etc. In the second round I was asked one problem on Kadane algorithm, questions on deadlock in OS and three way handshaking protocol of TCP. Since my answer was correct for all three,no further questions were asked.
The hr round was mostly based on the non technical skills mentioned in my resume. It was easy.

  • Q4. What is time complexity and how we measure
  • Ans. 

    Time complexity measures the amount of time an algorithm takes to complete as a function of the input size.

    • Time complexity is expressed using Big O notation (e.g., O(n), O(log n)).

    • It helps in comparing the efficiency of different algorithms.

    • For example, a linear search has O(n) time complexity, while a binary search has O(log n).
