Amazon Software Development Engineer(SDE II) interview questions

a recruiter contacted me on linked in and told me to apply for a this position and after applying and passing the coding test another recruiter sent me an email to provide them with 5 different availability times to have the interview and never contacted me back then I emailed the recruiter again she told me sorry for the inconvenience to send another 5 availability dates again and I did and again she never contacted me or even told me about any information about the interview , they never cared about the stress, the effort and the work that people do for passing their interviews.
