I was asked by HR things about my CV, then a few weeks later they canceled the role after I took the time to get ready for leet-code style interview.

Very honest process, they tell you from the beginning what to expect even compensation wise there is no surprise at the end because it was discussed during the first HR call. I had a 1 hr call with the manager, followed by a 2-3 hr take-home project, 30min call to discuss it, 1 hr call of design discussion, 1 hr of behavioral and finally a 30min with the chief of engineering as a formality.
