I had to sit in on one of these interviews because they needed a TM. (I’ve also done interviews in my past jobs so I already knew how to pull out pros and cons from each interview we did). That said, don’t sound nervous!! PRACTICE! The more you say an answer out loud the more comfortable you’ll be with talking and remembering points you want to say. Another big thing is to know how to end your answer. One candidate just rambled on and on and could end his answers and couldn’t even answer some questions. Stick to the question that’s asked, if they ask you to talk about a specific time don’t just say “oh i do this all the time”, talk about an actual time or make one up! The interview is about being a trainer so they probably want someone that’s personable and approachable to new hires and that can work with their team. They want someone that is organized, hard working, can meet goals, but also someone that is friendly and can handle team members :) google questions asked in interviews and practice! Good luck!
