Interview Preparation Tips

Interview preparation tips for other job seekers - Don't apply for this company. Main reason is strictly 5 days work from office. Hr are so much incompetent in terms of explaining the process as well as job role. Delayed response and rude behavior.bo feedback and not even shared the outcome of interview. Has to ask multiple times to receive response. Seems engineering department isn't capable enough to decide what they actually want from candidate and what should be the outcome of questions asked.

Round 1 - Technical 

(3 Questions)

  • Q1. How to check a number is power of 2
  • Ans. 

    To check if a number is a power of 2, we can use bitwise operations.

    • A power of 2 has only one bit set to 1, so we can use the bitwise AND operator to check if the number is a power of 2.

    • If n is a power of 2, then n & (n-1) will be 0.

    • For example, 8 (1000 in binary) is a power of 2, and 8 & 7 (0111 in binary) is 0.
