I applied through an employee referral. The process took 2 months. I interviewed at Shell (Houston, TX) in Jun 2013
Interview
While it took a long time, the process actually suited my skills very well. They provided a presentation topic and asked for a 1 hour presentation including time for questions. They also asked a number of questions on hypothetical situations including technical / leadership, and asked for examples in experience to back it up (though that was harder). Like everywhere, the interview process is a crap shoot and tends to focus on image, but at least there was a little more substance and not just 'can you can along with an HR person who only pretends to care and can't understand anyone technical'.
Interview questions [1]
Question 1
Imagine that you are the CEO of a company and a product your company has been blamed by a celebrity couple of causing an injury to their child. You have a press conference scheduled to address the situation tomorrow. How do you prepare for the press conference?
