There were 3 round of interview first was with recruiter company and after I had 3 hours off with vertex I really like it first was behavior question and technical and coding, at last, it was IQ

2 rounds till now. 1st was with the Recruiter / HR. She asked some basic questions about what i do and tried to match her requirements. 2nd was a phone interview with the Hiring Manager. He is supposed to be the reporting manager of this position. It went smooth. Asked for the technical background and related questions on my prior experience. Nothing unanswerable. This was around 30 mins. I was given opportunity to ask questions about Vertex as well. Waiting to see if I call for the next rounds
