We used git-mob in my team at Typeform, and besides the script still being a bit fiddly at the time, the overall experience was quite good, especialy with a mix of new and more seasoned developers involved.

What I recommend is increasing the rotation time to 25-30 m, especially initially.

The approach I'm experimenting with now is using vscode remote (ssh) and working with a shared remote workstation (running on EC2 and GCP).

Pros:

- no need to worry about sharing the same environment (all of you work off the same workstation after all)

- less infra: no need for external CI (you can just run the build scripts on the workstation, via commit-hooks).
