Amazon Software Development Engineer interview questions

Sent my resume to the recruiter, got invited into the first round of interviews. The recruiter told me to inform her if i didn’t apply on the job portal and then she would send me a link to apply as its a mandatory step. I sent her an email saying that i did not apply then i never got a reply on that but i still went ahead and did the online assessment. A few days later the recruiter reached out saying i made it to the second interview without acknowledging my previous emails. I did the second interview a few weeks ago and still did not get any feedback on it. I decided to email the recruiter a week after i did the interview but never got a reply back. I consider this a rejection however i do not really think that not getting a reply back from the recruiter is a professional way to handle things.
