Very quick and kind. I have done the first call with a recruiter. And then a Java test. Above all, I appreciated Mark's feedback to my solution: complete, clear and fast reply(my solution, by the way, sucked. I didn't realize that I could use the internet and library like any work of every day. I faced it as a college exam and anyway I messed up. Especially with regex. All experience for the future) Overall a good experience.
