I applied through an employee referral. The process took 2 months. I interviewed at Siemens (Calgary, AB) in Feb 2009
Interview
The initial interview is with 2 managers from the department and 1 person from HR. The questions are lengthy and deal a lot with situations and procedures you incorporate in problem solving. They will ask you to provide a salry expected and try not to go over the top as they won't call you back. Expect very long wait time before any more communication. Typically the whole process takes 2-3 months.
Interview questions [1]
Question 1
As they are very worried about perception and compliance within the workforce, be expected to be asked very strict questions about compliance, ie. work place violence, sexual harrassment, equality etc.
