How to deal with persistent recruiter still contacting me after declining offer


    So I recently declined an offer from a recruiter, it got to the final stage where offer was on the table but I said no. The company was big, salary was fantastic but I didn’t want to work with the technology they were using as it was very niche. I communicated my reasons for declining the offer to the recruiter various times now. He has emailed and called me several times and I’ve been ignoring it. He even went as far as get his senior to contact me to see if they can change my mind. It has reached a point that it’s starting to feel like harassment and I’m not sure what I should do.

    How can I get him to stop trying to convince me? I don’t want to burn any bridges as the recruiter could be useful for finding a job in the future.
