I applied online. I interviewed at Principal Financial Group in Nov 2015
Interview
Mainly behavioral. Zero coding questions. I only had a phone screen. There were 2 sets of software developers who interviewed me through phone. Basically asked the same questions (all behavioral). It would be a plus if you had experience using Java/C#, as this is what the company uses.
Interview questions [1]
Question 1
Talk about a technical challenge you once had in a group before, and how did you approach it?
