Informativ interview questions

The whole process took about a month. Initial phone screening, video interview with direct report, another video interview with direct report and team member, then an in-person meeting with direct report. I received positive feedback after each interview. After the last interview, they told me I’d hear something within the week. Two weeks went by and heard nothing. I emailed the direct report with no response. I had to text the HR coordinator to finally find out I wasn’t selected. I know this isn’t unique to Informativ, but it’s so unprofessional and disappointing that people/companies still do that. I’m an adult and can take rejection, I’d expect seasoned professionals to be the same.
