      Backend Developer Interview

      Jul 31, 2024
      Anonymous interview candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at PhysicsWallah in Jul 2024

      Interview

      I recently interviewed for a position and found several aspects of the process concerning: Interview Conduct: The interviewer's voice was unclear, which made it difficult to understand the questions. Many questions were poorly explained and appeared to be based on misconceptions. The interviewer frequently used vague responses like "no no" when adding conditions to existing problems, instead of clearly stating additional requirements. This approach made it challenging to fully grasp the evolving parameters of the questions.

      Interview questions [8]
