Just to chime in: I'm a PhD student in CS/machine learning with a competitive enough CV to interview anywhere, and I have gone through the motions at many companies previously (e.g. for interning), and there is nothing I hate more than coding interviews.
It literally makes me hate companies, it turns me off from interviewing at a place, and it makes me deeply resent them even if I get an offer after a ridiculous series of interviews.
After you have subjected me to a terrible/demeaning interview process, I might still work for you, but I will never be a loyal or feel any inclination to contribute more than I need for personal gain, because you have established that nature of the relationship via the interview. Sorry for the rant.
I think you need to grow up some and experience this from the other side. In the past I've felt the same kind of contempt for this process, but after having experienced being on the other side I respect the difficulty in identifying(accuratly) good candidates.
Honestly I don't think I need to do, I have interviewed many people for doing very code heavy research projects and not once have I felt asking them to do a white-board code exercise would have contributed to my evaluation meaningfully.

I hope you succeed, so very much.
