It is not possible to cancel your request after you have clicked the "I'm interested" button.
If you click 'I'm interested!' and get a message from a company that you are no longer interested in, you can just let them know with a quick message via chat.
The 'I'm interested' button is not a formal application, so there is no pressure on you to proceed with meeting the company unless you want to!
Your status on Wantedly is not affected if you choose not to meet.
If you are still having trouble, contact Wantedly Customer Relations Team from here!
