Met with HR, she asked questions and i answered all of them. The only thing is that i never worked with Jira, and i told her that i will learn it pretty fast because i worked with similar softwares. i took a course of Jira right after the interview, followed up with HR and told her that, however did not receive any reply. After finishing a course (in a week) i followed up again and did not receive any reply again... After that, i felt that Plastic mobile does not really care about candidates, their feelings and emotions. It would be fine to reply "we found someone better", but not to reply at all (twice!) is rude i think...
