Booz Allen Hamilton Software Developer interview questions

I was referred by a current employee. The first portion of the interview process was a 1 hour tech screen involving programming questions. Once passed, there was a 3 hour in person interview for behavioral questions and to see if I would fit in.

It was three back to back in person interviews each about 30-40 minutes. Mostly behavior questions, questions about my past projects and some basic OOP questions. 1 example of code was provided, had to debug it if anything was wrong with it and explain its time complexity. Very informative and nice interviewers,
