Ericsson Software Engineer interview questions

I applied to the position in June and received an email in July that I was selected for the next procedure which I will be informed about in the middle of August. I invited to HR interview with a 3rd party company. The interview was good and the HR told me that he will suggest me. I invited to manager interview at Ericsson 1 month later. After manager interview they wanted me to take a test in October. After the test they wanted to make a second manager interview as a second opinion. The process ended in November which I was informed that the recruitment process has been cancelled and therefore they could not opportunity to offer me a position.
