Western Union Data Science interview questions

There were three interviews which went quite well, also had a task which. Didn't get the job and probably still wouldn't have hard from them - got no response after several weeks and a couple of emails I sent. Found out I didn't get the job only when I called them. Also I know that one of my colleagues at the company I was working at was contacted regarding me and my skill set - that was extremely unprofessional as my former company found out I was looking for another job.
