I received a call from recruitment agency. The recruiter told me there is job vacancy and will pass my resume to company.
After some weeks, received a call from agency to schedule an interview. I did some research, saw it was the IT industry, and I told the recruiter I wouldn't be going to the interview. (I'm not interested in IT)
He messaged and asked me if another date would work and gave me options for other dates. I told him I'd decide later and tell him. He repeatedly messaged me and asking for a decision. When i didn't reply he called multiple times, even at 9+ at night. To stop him I told one date which is Friday.
He called the next day as well. I blocked him as he was not listening to me.
As the interview date approached, he kept on calling and messaging, but I blocked him. Then he messaged from another number and was angry that I did not respond and he demanded to know why. I said I got another job and blocked.
How could I have more effectively communicated my non-interest, and how could I have better handled his pushy attitude?
