Applied for the position through LinkedIn mid-August. A week later I was contacted by a Vertex Talent Acquisition Consultant to arrange a phone screen but it took two weeks to get that organized. After that interview, it took another two weeks to arrange a call with the hiring manager. Then, there was radio silence (despite regular follow-up communications on my part) for a month. Another associate TAC contacted me to arrange a 1/2 day f2f interview. I met with 6 people that day (and thought all of the interviews went well). A month later, I haven't heard anything from anyone, despite 3 follow-up emails. This is typical of Vertex. I applied for a similar role in a different department over two years ago and had exactly the same experience. I'm not sure that even if an offer came through at this point that I would take it. I've learned the hard way that the interviewing/hiring process are pretty indicative of how organizations treats its employees.
