Amazon

After being contacted by a recruiter, I was asked to fill out an online application with my resume and experiences. Afterwards, I was sent a technical screening, which I had two weeks to complete, in addition to a behavioral screening.

Good, long but straightforward. It has multiple stages. You can prepare for this online and from other sources. They are on time and very understanding. Know your design patterns and algorithms, and know how to communicate to Amazon's standards.

This was for a boomerang interview at Amazon. Since I am returning to the company within a year, there was no OA and no coding rounds. Just a one-hour interview, which was the bar raiser.
