BAE Systems Cyber Researcher interview questions

Two half hour telephone interviews, one two hour interview. Telephone interviews were both late in calling. Two hour interview extremely short notice before weekend (Friday late) with interview Monday Morning - so preparation was over weekend after a long work week. Ridiculous. Positive feedback from first interviews, made me put other things on hold; After last interview absolutely no communication. Extremely inconsiderate and unprofessional - avoid applying, time wasters. No response to follow up emails I sent to themselves or recruiters (Evolution), who seemed in a rush to collect surveys, no doubt as they knew I would receive no further contact. I would advise to avoid as their recruitment process is shambolic.
