Niantic 2nd round interviews

I recently passed Niantic's first screening for a backend role and moving on to the 2nd round of interviews. I was told by the recruiter that I'd be going through more Leetcodish rounds, but after scheduling, the coordinator got back to me with rounds labelled differently, ones with "Coding General", and another with "Coding Infra". What's the distinction, and am I expected to actually code cloud infrastructure in the "Coding Infra" one? I hope not, things are kinda looking bleak for me. TC: 0 YOE: 3
