1 interview with Mantel, then 1 interview with the customer. I think it depends on the client if they want to interview the consultant. The interview with Mantel was good. I sent one of my GitHub projects and we discussed it during the interview. Only one interview! That is how it should be.

They went quiet after the interview and got ghosted. Thankfully understood their culture and red flags prior
