What happens in the kernel when an interrupt signal is sent to a process?

When I run a command that takes very long in terminal and want to kill it before it finishes, I press control-c to send an interrupt signal to the process. I'm assuming this signal is first picked up by the keyboard driver and it writes the signal to some file and the kernel picks it up and then kills the running process in terminal. Is that correct? How does the event loop work in Unix in this case(signal handling in Unix is mentioned in Wikipedia page for event loop)?
