Multiple interviews then ghosted

It's been a while since I've had to interview, have only gone through it once since COVID. I'm an experienced engineer, but had the same experience at Oracle, PIMCO, and Visa. First of all, let's just say I'm qualified for the positions I'm interviewing for. Most of the coding and system design stuff is a walk in the park, and my experience is in Fintech. Here's a pattern I'm seeing now: 1. Make it past chats with the recruiter, gain contact info for the recruiter, get interviews set up. 2. Complete 3-4 rounds of interviews over the course of about a month. 3. Wait a ridiculously long time with no feedback, no path forward, no timelines, nothing. With Visa, talent acquisition stayed in contact for about 2 months AFTER interviews, telling me to wait and specifically telling me that the VP had not provided feedback yet and was being pinged. All interviewers were Indian, I'm not Indian. PIMCO, same thing, entire interview pipeline Indian, and likely the entire engineering group Indian. Completely ghosted, no feedback from TA or VP assistant who was scheduling with the VP. Oracle, not 100% Indian, but the ones who weren't were 25 year veterans of acquired companies. TA ghosted me, I sent some salty emails and she finally responded telling me they were moving on. If they know this is unethical practice, what's the purpose? It has to be something to do with liability. If you won't provide feedback, it's not officially a denial, they just wait for you to go away. Sure looks like non-Indians aren't getting a fair shake at these large firms. Isn't this illegal? Do shareholders care?
