With the latest update of Google from 7 March 2018, I don't think that guest blog posting is effective. I highly doubt because I work with networks with over 400+ domains and I see drastic changes even on so-called High Authority websites. They drop on rankings and also traffic.

So to answer your question above, I don't think that this works anymore.

Definitely, the answer is yes. Guest blogging is my primary SEO technique to get traffic and link juice from top blogging sites.

It's definitely one of the most effective techniques in SEO, one thing you should always remember is to properly choose the anchor text.
