Cisco Product Manager interview questions

Had an initial phone screen that was very much like a consulting interview (market sizing, etc). 30 days later I was contacted again to interview for a different position. Only one round with 5 interviews including sales, engineering, but mostly product managers. One group interview where I presented a business problem to the PM leadership. The interview questions consisted of grilling on the product domain I would be working in (even though I had little background in it -- good thing i did my research), brainteasers (what's the TAM for dryers in the US), and how to sell questions ("sell me something in the room").
