SPARC Software Developer interview questions

A SPARC Recruiter contacted me via LinkedIn. We had a good chat after agreeing to speak. They set up a code challenge sort of thing, which I did. The challenge was very problematic. Nothing worked right in getting the code and instructions to me, or in submitting it. The recruiter did not attempt to contact me after that. I contacted her, and she still wanted me to come out for an interview. Or at least that's what she said. Never heard from her again. I didn't want to waste my time speaking or dealing with SAPRC again in any way. The entire company comes off as very "too cool for school" and from the people I know who have worked there in the past, they're anything but. The recruiters were very unprofessional. Maybe Booz Allen Hamilton will turn things around?
