I give "easy" interviews to people that have shown signs that I can trust their technical work. I far more interested in their communication and organizational skills once we get past the technical aspect of it. As well as their higher level "engineering" experience. What I mean by this is- when we're planning a complex feature, I want someone that has the experience and communication skills to stand up to the team and not be a yes man, point out potential issues and concerns and propose better ideas. Leetcode is not an indicator of this. The interview may feel easy to the person being interviewed, in the sense that there isn't wrong answers, rather, there could be an absence of correct answers.
