I had made that transition a few years ago and haven't looked back. I honestly didn't have too much issue with the transition or the interviews, I was transparent in why I wanted to go back to IC over people management, but made sure to avoid saying why I didn't like management and instead focused on why I liked IC work more. It's a fairly common transition to go back once you learn more about the people management side of things, so I don't think you'll have too much issue justifying it. I think the biggest thing that companies really honed in on was my ability to become an IC again and not overstep into management duties, which was not an issue for me but can be for some people.
