These things tend to come in waves and trends.
Sometimes firms feels like they have to push their processes earlier to compete with other firms, only to find out that approach starts to harm them in other ways (eg if you complete earlier you may just have higher renege/drop out rates, or end up rejecting good applicants who are just a bit more “green” to recruitment processes).
It might be that they are monitoring things more closely too. It’s much more common to look at things like your diversity of hires during a live recruiting process now rather than just waiting for the cycle to complete and doing it retrospectively. If the diversity of candidates is not there, they might be doing more attraction work to try and get those diverse applicants into their pipeline.
