It seemed like Ritesh was being recorded without his consent, so I don't think it's fair to take this interview(?) as a confirmation of election interference. It seems like he's saying google's results intentionally favor one candidate over another, which if we assume that to be true doesn't speak of Google's interference, it simply points to Google's search optimizing clicks. It's not like it's terribly difficult to find content in Google that is for either candidate or against either candidate.
