I applied online. The process took 4 weeks. I interviewed at Principal Financial Group in Jan 2015
Interview
Applied online through Career Website. Was contacted via phone by an HR recruiter to set up an initial phone screening. Screening questions all pertained to work availability and desired compensation. A couple weeks later I was contacted by the same HR recruiter to set up an interview with the Hiring Manager via phone (If your more than an hour or two away Principal won't bring you in for an interview). Basic behavioral questions asking you to describe a time when you worked through a group conflict or when you faced a difficult situation at work or school and how you resolved it, etc. No technical questions.
Interview questions [1]
Question 1
Describe a situation, either at work or school, where you had to make a difficult decision.
