I made a search form for YouTube with advanced search filters: https://playlists.at/youtube/search/
A couple alternatives I use are DuckDuckGo's video search or using the 'site:youtube.com' search operator in Google.
He was interviewed by some journalist.
The problem is the you can't eve filter by time published now and there are alot of off topic videos in the search results. Along with trash YouTube Shorts videos.
