Highbury Defense Group interview questions

I received an email from a recruiter, expressing interest after seeing my profile on a different social media portal. We had a promising phone conversation and the recruiter exemplified that I was a person suitable and adequate for the role they were trying to fill. My skillset was what they were looking for. The recruiter requested my resume and told me he would setup an interview with the team. I had to quickly update my resume. After emailing my resume, I did not hear back from the recruiter. I only heard back one week after, expressing apologies for the delay in getting back to me due to unfortunate circumstances and that he would contact me again the following week. If and when he did contacted me, it was a for a 'quick call' unfortunately I was not available due to personal reasons. I requested we schedule a formal call on a date and time that would work. But he never got back to me. So I gave up. The experience was mostly negative. I provided what he requested and stood by only to never hear back. It became an unprofessional and disappointing experience. I had asked colleagues if they had heard of HDG, everything was postive and well-recommended. My experience was the opposite.
