Hey! I think it's quite the opposite, and I'll explain why.
Let me just apply one example. A few years ago I was screening candidates over a 30-minute live coding interview covering pretty day to day stuff. That required a 30 minute investment from the applicant in what is a high-stress situation for many. I can't tell you how many times they seemed very stressed simply because they had to code in a live interview setting knowing someone is actively watching what they are doing.
Now compare that to a 20-minute screening interview where most of that pressure is gone. You can do it whenever you want to.
That is my rationale behind it, thinking both as an applicant and as a hiring manager.

Why do you think this leads to more wasted time?
