I applied to Amazon using a referrer and they sent an OA(June). I attempted the OA in mid June. There were two questions and I was able to pass all the test cases for those.
Since then I have not received any follow up after that, however one other Amazon HR mailed me for another job opportunity(most probably automated one).
I have mailed the HR a few times but no reply. No rejection/next round mail.
Is it silent rejection or is there hope?
What would be the best way to get follow up?
