Amazon Solutions Architect interview questions

first interview is a basic phone call with recruiter where they explore simple employee behavioral fit and ask basic technical questions such as: "what linux command is used to search for someting" 2nd interview was with an SA manager. My problem with this interview process is that they give you a variety of technical topics to learn, and say that they may ask you a few questions from the topics they provide. Then in the actual interview they ask none of the questions they said they would. Instead they did a deep dive of the resume you provide and ask questions they feel like you will have trouble answering.
