Cognitran Project Manager interview questions

2nd interview was mainly on agile methodologies, use of Rally/Jira, architecture design, responsive design, xml, html. Previous job, why Cognitran and then they gave me an exercise to do.... Scenario: selling an mp3 player. I had to talk them through the design, the sales pitch, what content will be covered on the website about the mp3 player, who will build the website, what tools are needed to build the website, will the website be responsive, how much traffic will flow through the website, how will you manage the traffic on a website. Interview was difficult, 3 people, 2good cops, 1 really bad cop, it went well, got an offer following day.
