Followed by a general behavioral discussion. Took two weeks to get the complete process completed and got to sit with manager, team members, VP of engineer and engineering head.

I couldn't really disclose the questions as this will be against the policy of Panasonic, but I will suggest that everything is based on how you perform things in every day development from architecture level to end to end development to improving the efficiency of the application by removing bottlenecks.

There is nothing to fear, just be yourself and implement the best practice you feel would be.
