Northrop Grumman interview questions

Coding test, solve about 4 problems using python and java. Also a few questions about using java libraries like stream and other about oop features of java. Poor communication, 2 months after interview still no response and when I emailed to enquire about it they replied with a rejection

Friendly and. Nice staff . Easy going managers and who know about job requirements. So questions were straight forward. Three people interviewed and all were good and friendly. This was one of the good experiences I had
