I have the same experience. Interviews are very time consuming (prep 30 min, interview 1h, fill out the feedback form 30m-1h), and having several interviews each week means I spend ~1 day weekly on something that's not going to benefit me directly in any way (excluding the benefit of potentially working with good engineers I helped hiring).
So unless the incentives change, I don't see this process improving in big tech.
