      Easy interview

      Application

      I applied through a staffing agency. The process took 2 weeks. I interviewed at Thales (Jurong West New Town, ) in Feb 2023

      Interview

      I attended interview through teams February 2023 for Software Engineer BPS cards Singapore. Interviewed by manager and Team lead. They mainly focus on Bit manipulation and how u approach to solve it? Interviewed for the BPS cards team. Mostly C questions. Prepare well with ur resume.

      Interview questions [5]

      Question 1

      1. You are given two 32 bit numbers, N and M, and two bit positions, I and J. Write a method to insert M into N such that M starts at bit J and ends at bit I. You can assume that bits J through I have enough space to fit all of M. That is if M = 10011, you can assume that there are at least 5 bits between J and I. You would not, for example, have J=3 and I=2, because M could not fully fit between bit 3 and bit 2. EXAMPLE Input: N=10000000000, M=10011, I=2, J=6 Output: N=10001001100
      Answer question

      Question 2

      2. There is a building of 100 floors. If an egg drops from Nth floor or above, it will break. If it’s dropped from any floor below, it will not break. You’re give two eggs. Find N, while minimizing the number of drops for the worst case. Please find the answer and implement code which simulate your answer. 
      Answer question
