Cisco interview questions

I had one on campus interview which constituted of basic questions regarding multiple process handling, race conditions, use of Montiors in multi threaded programming. Next interview consisted of 1-1 interview where I was asked about my courses and aptitude questions. Also, there were questions related to networking basics and my past projects and experience.

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").
