The manager asked me to write a job description for this role based on my experience, which they published internally and externally and I had to apply to. They then invited me to an interview, where we just discussed business as usual like in our weekly catch up, it was not an interview at all. At the end of the 30 minutes, the manager wrote to HR to offer me the job. This is very common practise in Unilever, and why it's often useless to apply to vacancies you see on the internal or external job site.
