Northrop Grumman interview questions

Very in depth process requiring to recall day to day activities and how to overcome certain issues that arise unexpectedly. The rest was very standard with a few curve balls like any interview but this want long winded or a time waste.

One hour phone screen. Several STAR behavioral type questions. Then easy open ended technical questions. How do you verify good results from FEA software (hand calcs). Note this was for an internal transfer.
