Complete nonsense, it is a four interview process where you are dragged through a meeting with hiring manager, meeting with business director, case study with BDR manager, and meeting with CRO. The process is tedious for a sales role, and in my case I was denied after the final interview. The reasons they gave me were trivial because they are reasons that wouldn’t have allowed me to make it past the second round. Make sure to talk about a book, I did in 3/4 interviews and apparently not mentioning it in the fourth was the reason for their decision.
