Refurbed Technical Lead interview questions

After 1 month of interviews, including a take-home technical challenge, there was a plot twist. They offered me a position as a plain developer. I was aiming at being a Tech Lead, which is what the recruiter promised when he contacted me. And what's worse, they took a full month to complete this deception, hoping that making a good economic effort would justify and somehow erase my motivation. They maybe thought money would "put me in my place"? Insulting.
