Be prepared to be interviewed by people who, in my experience, did not seem especially interested in hiring anyone — let alone in understanding what seniority actually looks like.
Expect to still be put through a coding challenge and judged through the limits of their own understanding, rather than the level you are actually operating at. Their titles may sound impressive, and maybe they are within the narrow context of that team, but the technical maturity I encountered was low enough that normal engineering reasoning barely seemed to register. Alternative solutions were not really evaluated; they were dismissed as if any deviation from their preferred approach meant you lacked knowledge.
To their credit, they were open about the high turnover of developers in recent years. Given the atmosphere, that was not hard to understand. My impression was of an environment where a couple of people had managed to gather far too much influence, while senior leadership either did not see it or did not understand what was actually going on.
For me, it was a complete waste of time. I would not go near it again.
