It began with the typical screening interview by HR. Basic experiential questions asked (knowledge of cloud hosting, position relevant questions). A week later a phone interview in which the questions were primarily skill based and were basic applied statistical questions that would be asked of folks who know they need this skillset, but don't know how to test expertise. For most self-titled 'Analysts' though, these questions would weed them out quickly. The next step was an on-campus interview. Be prepared to spend a day. I was there for 6 hours. The questions then went into statistical inference from financial data during one hour, the rest regarded demonstrations of fit within the culture of Rackspace. Questions are all evidence-based. The interviews are purposefully long, as to break down the stamina of folks who can otherwise fake through an interview. I was asked to attend a second interview, where I was asked maybe 2 or 3 fit type questions (I think just to round up HR as I believe they wished to hire me in person - I was transparent about another offer pending). My hiring manager then left the room, and came back with a bouquet of dusty plastic flowers and an HR person with the contract and offered it to me on the spot.
