Venn Strategies interview questions

I applied online at Indeed.com and received a phone call a few days later setting up the interview. I interviewed with two Vice Presidents, one of which was wearing a hooded sweatshirt and his kids were visible during the interview. To me, this was extremely unprofessional and just shows a total lack of respect for me and my time as a potential candidate. I guarantee if I wore a hoodie, I would no longer be considered a candidate. I've been unemployed since March and need a job, but if this VP doesn't respect my time as a candidate, how would I be treated as an actual employee?
