Amazon Web Services Mobile Engineer interview questions

One recruiter sent me couple of emails and suddenly escalated to the hiring manager talk. They asked me my availabilities so I sent them my schedule. I told them that I’ve never talked any of the recruiters, so I don’t have any information about the role. One of them called me after my email and we talked about the position and the interview process. They asked my availability again after the call so I sent it. Then they ditched me. I’m leaving a review because their hiring process seems like a pure mess.
