Amazon Sr. Product Manager interview questions

2 rounds of phone interview followed by on-site. Then a written assignment due in 24 hrs. The HR recruiters at amazon are notoriously bad. You have to really keep an eye on them and push them to communicate back. They are super disorganized and often do not follow up on promises. Also, the HR interfaces have no idea about what the actual hiring team is looking for and have basically no helpful advice or insight about the interview process other than what they were trained to repeat from boiler plate response.
