First step: computer based test of quantitative and written skills. Questions are directly linked to what you'll be doing day to day. Second/third steps: phone interview then 1-1 then panel interview with team. Hiring can be a long process since senior staff is often traveling. Once hired, not much room for negotiation and start date pretty much immediate.
