Initial recruiter screen was with a member of the offshore operations team, who get online around 7pm PT. She was OK to talk to, but pretty clearly was just filling out a form and trying to match some listed keywords against my answers, and seemed like she wanted to get off the call ASAP. Since the interview was during typical dinner time I asked about their working hours which is when she told me she was offshore, and also that they work more than 40 hours a week, 4 days in office, only Thursdays WFH. The job description said they work "a couple of days a week" in office, so I'm not sure if that's a difference between their offshore and US office, or if the job description is just lying.
The interviewer for the technical screen was worst communicator/collaborator I've ever interacted with. When asking me questions he'd immediately interrupt my answers, and when I asked him questions he acted as if he didn't even hear me. On several occasions I asked him clarifying questions about ambiguity in the prompt, and it took 2-3 times each before he acknowledged that I was speaking to him, which then prompted another 3-5 rounds of back and forth before getting an answer to my simple questions. We're talking things like "the prompt says 'return an answer', what if there are multiple valid answers? return the first one? any of them? what if there are no answers?" My sense is that he thought he was a proctor, with the sole purpose of monitoring me to make sure I didn't cheat while silently grinding out some code, not a potential future teammate to evaluate what it'd be like working with.
