first interview will be via telephone and will last 45 min to 60 min. You will have a person asking questions concerning your life, future endeavors and getting to know you better with small talk. After that you will be asked questions about computers, dos,networking, cmd how to get inside of the operating system to enter command prompts. the next round will be speaking about any experience with mechanical and electrical maintenance. The interviewer will ask you to explain certain procedures to show your knowledge. Pretty easy stuff if you know your skill set. warning if you don't know just say i'm a bit rusty o that topic but I will research and get up to speed with a purpose.
