I had one interview with HR, another with an SEO Editor, and another with the SEO Manager.
After that, I did one more interview with the HR Manager and a last one with the Founder. It was a long process, but it was enough for me to understand the company's dynamics and trust it. In addition, I had to take a test of my SEO knowledge.
I reiterate that I was referred by a coworker from a previous company, but I still had to go through the entire process.
