Optus Associate Director interview questions

Lengthy process with limited communication between when an interview was held and then finding out if I had made it to the next round. I assumed on at least 2 occasions I hadn't been successful given how long it took to come back to me. In total there were 4 interviews spanning almost 3 months. Each interview itself was pretty straight forward in terms of questions around professional and technical skills. I ended up finding out I wasn't the successful candidate after directly contacting Optus to say that given the length of time that had passed that I assumed I wasn't successful but if I could please get some feedback to help me with any future opportunities. I enjoyed the interview process as a whole as everyone I met was very friendly and wanted to help you do your best in the interview. I would have enjoyed working in this team. But the lack of communication and feedback just let things down, particularly after all the effort that went into preparing for each meet and greet. I also would have liked to have been given feedback directly from the hiring manager who I met with twice and who I felt that I had a good rapport with off the back of some good and exciting discussions about the product and team growth.
