      Three Phases: 1. HR Initial interview with basic electrical and electromotor theory to gather whether employee has understanding of basic electricity and mechanical operations. 2. Interview with hiring manager to get a deeper better understanding of if they understand the job: UPS, Electrical power generation, power supply, A/C and HVAC, Evaporative cooling, generator theory, etc. And typical HR questions based off of Leadership Principles of Amazon 3. Interview either in person or on Amazon Chime with even more in depth or thorough of what the hiring manager talked to you about. You can interview with 3-5 people at this time all separate and ask different questions.

      Accepted offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 2 months. I interviewed at Amazon (Cape Town) in Nov 2021

      Interview

      The process involves six interviews, which may ultimately lead candidates to question the value of their efforts and the necessity of pursuing this opportunity. The work environment fosters a culture of overwork and unrealistic expectations, leaving employees feeling undervalued and constantly questioning their worth, which undermines morale and productivity.

      Interview questions [1]

      Question 1

      Please describe a situation in which you experienced a misunderstanding with a colleague and explain how you resolved it.
