My immediate reaction to the title of the article was "... for SWEs and possibly SREs".

But to answer your question, yes, absolutely.

Any ideas what the process would look like for something like Solution Architect for Google Cloud? I can’t imagine that there would be graphs and tree coding questions but you never know.

I think it largely depends on the person interviewing you. I know candidates interviewing for Machine Learning positions get asked with typical algorithm questions.
