I applied online. After about a week or two, a recruiter from Amazon phoned me and we spoke for about 45 minutes. He was very pleasant to speak to, we covered some basics around the role and its expectations, and he laid out the next steps in the interview process, including the STAR method. The second step was a line manager interview where he focused on details of past projects and lessons / outcomes. The next step (which I didn't make it to) would have consisted of several interviewers asking different types of questions, and at this stage you don't need to satisfy each interviewer. I presume after this they give you a result. Much of what is documented online aligns with my experiences.
