I've seen their implementation. It was horrible. We eventually took the project away from them and had the local team work on it.
Also a fun story: they didn't use version control at all. When we eventually forced them to use git, they put the whole codebase in a .zip file and committed that.
I've worked with offshore companies that are similarly as bad, but then again there have been some that have been excellent. In your case, I don't know how they lasted 6 months if they're not committing to git etc, if that's the standard. They should be brought into the daily standups as 6 months to wait for some delivery seems a bit waterfally (apologies if this is a mischaracterisation).

At least it it a clear mischaracterisation of waterfall:
