Insight Global CSR interview questions

Recruiter reached out over LinkedIn. Had video call that felt unprofessional. I had a second call the next day that also felt unprofessional. Finally, after they reached out to schedule the next call, I responded with availability and then was ghosted…super unprofessional. I read other reviews speaking to ghosting as well which makes me think if this is how you treat applicants, how do you treat employees?
