The Predictive Index Senior Software Engineer Full Stack interview questions

I usually don't write reviews for reasonable companies, but PI was really unprofessional so I decided to write down about how I was treated in their interview process. First, received a message from Linkedin saying my background looks like a fit for their Senior Software Engineer - Full Stack position. Asked if I want to apply. Replied 'Yes'. Then they sent out 2 assessments: a behavioral assessment and a cognitive assessment. Completed them in 2 days. Asked what's next. Waited a couple days. They replied and asking me to complete another cognitive assessment saying people were usually given a 2nd chance to complete it. Completed it again. Waited 1 week and heard nothing. Follow up with the recruiter. No reply. Until one day (Tuesday) another recruiter from PI contacted me saying they want to set up a call with me. And she scheduled it to the coming Friday. The recruiter called 8 minutes late per our scheduled time. She sounded uninterested and asked a few standard questions. Mentioned my behavioral assessment result indicated I was the person they were looking for. This was on a Friday. On Sunday, I received a template email saying "We are not moving forward with your candidacy for the role". Until now, the whole process took 3+ weeks. It looks like they just want some free users to test out their products. Not interested in hiring people at all given the lack of response they showed.
