Insight Global Various Roles interview questions

I've interviewed with hiring teams from two different companies for contract roles via Insight Global. In both cases I never heard from the recruiter afterwards. For the second company, I had even phoned the account manager directly after my interview with the hiring team as he had requested that. For the first company, after I had interviewed with the two hiring managers I received the same initial LinkedIn message from the Insight Global recruiter asking if I would be interested in the role. I genuinely thought that she had made a mistake and I responded to her message asking if she had sent it by mistake and then reminding her that I had just interviewed with the hiring team that day and that the hiring manager had mentioned that he would be speaking with her directly after our call. I also asked if she had spoken with him since my interview. I never received a response from her. I'm posting this review as a warning to others NOT to expect a response from recruiters after your interview with the hiring company if it turns out that the hiring company does not want to proceed with your candidacy. But that said, I will continue to respond to recruiters from Insight Global because at least I have been able to get interviews with their clients AND it seems that they are exclusively engaged by some clients for contract roles (meaning that for the two roles I interviewed for, I did not see other staffing agencies advertising the same roles).
