Got contacted by the recruiter. Coding challenge was average. After that got invited for an onsite interview. Signed NDA, so can't reveal exact questions, but brush up Data Structures and Algorithms. They also give focus on behavioral questions (especially Amazon Leadership Principles).
Unfortunately, no offer is made. 3 coding interviews went well, but I think royally bombed system design question. And as an SDE-II, you should be good at it.
Tempe team is friendly and helpful. Overall good experience. Maybe someday I will meet them again. ;)
