Principal Financial Group Software Developer interview questions

Initial phone call with recruiter happened about 2 weeks after applying. Standard questions but I got the impression that they have a slightly odd work culture. At the end of it, the recruiter indicated that for the next step I will be invited for a 2 hour interview. The company has since disappeared. Very unprofessional - I don't mind a 'No' but if you wasted my time at least have the courtesy to follow up. Speaks volumes about your company's culture.

Behavior, coding 2 rounds. First round was a senior engineer and a manager asking questions and writing code. Then the entire software team asking questions and writing code for. Mix of behavior and coding questions.
