It was very very easy even for me whos not been doing it for long. Questions like how would you diagnose an abs fault, how would you wire up a set of beacons. Obviously mention things like fuse, relays ect and what wire you wire upto which pin on relay and what the pins do. They asked how i find out what fuse i need. Things like ohms law and the power triangle. A lot of heath and safety things, mention about cleaning your work area after ect. How you connect and disconnect a battery charger. If you mention about soldering make sure you say you would do it in a well ventilated area haha. Really easy to be honest and really laid back. How would you test a charging system, how would you diagnose a starting fault for example a none start. And you just talk through your steps. Nothing to worry about to be honest, lasted a couple of hours. If its over zoom at home make sure nobodys in the room with you and that you dont have notes all over place because they ask you to move your camera around every 30 mins or so haha. They was a couple of things i forgot and i just said im not sure they wasnt a problem and they kind of help you. Theys only one person doing the interview and then another person pops on every 30 mins to check nobodys in the room with you ect.
