Keep your answer focused on you and what you loved about your last job. Be honest about what you liked least, but stay focused on the positives. For example, saying that the leadership was toxic will indicate that you might have issues with people in positions of authority. Saying that you liked the break room the least at your last job and that the refrigerator kept breaking down says something different.

Focus on the positive impact you made on your work environment, which demonstrates the positive, collaborative impact you'll make beyond the team.

"After a while, I stopped feeling challenged in my former position, and there was no growth opportunity. I achieved the goal I set out to accomplish and gained some great hands-on experience. Once I got to know the work, there was nothing new, and I didn't feel challenged. It felt like the goal was maintaining the status quo, which didn't feel conducive to innovation. It was the right job right then, but all parties were aware of that going into the work. I have nothing negative to say. I just prefer to feel challenged."
