First, showing achievements on a CV isn't a trend.
Second, you can't "just interview well" if your CV doesn't give someone an inkling you might be able to do the job.
Third, "being the right fit for the job" includes being able to learn and being able to communicate. A CV that doesn't list accomplishments signals negatively for both of those.
Well, I've never heard of listing "achievements" on your resume, and all the articles I see on Google related to this are from Winter and Spring 2021, so at least that verbage is a current fad.
I'd consider someone with a pretty trendy CV to be a net negative, it means they endlessly focus on whatever is the latest thing, and not focusing on core principles, but many companies just want to hire people who spend hours optimizing minutiae and ignoring substantial fundamental issues; so this is actually rock solid advice!
Listing achievements/accomplishments/results/whatever, as specifically as possible, has been absolutely standard resume advice for decades. Maybe "achievements" is a trendy term. I don't know as I haven't updated my resume for over 10 years. But the point is that it matters more that you accomplished something specific than that you had this job.
I just get tired of seeing resume formats constantly cycling every year around some vague "trend". People adding headers and sections to their resumes outside of a simple straightforward standard, weird resume advice blogs and on YouTube are probably just desperate for constant content.

The advice is good now, but it was also good 15+ years ago. The 2004 edition of 'Cover letter magic' contains a heading "Sales and Merchandising: What You Have Accomplished". It says:
"You can most positively position your qualifications by defining the scope of your responsibilities and then highlighting your achievements and successes. That means not just saying what you did, but also how well you did it."
Note the use of the words 'accomplished', 'achievements', 'successes'.
