Rolls-Royce interview questions

Very mechanic interview, following the usual standard process and questions. Manufacturing experience is usually appreciated and many questions are around this topic. Engineers are highly valued as potential candidates even though for a buyer role, even a strategic buyer, in Poland - they accept juniors or with zero experience. Mainly because the local market in Poland doesnt have too many Procurement specialist in any field really.

The overall process took a lot of time. I got a first interview call from HR which was just a pre-screening interview asking basic stuff why I want to leave my current job. The second interview came 2 weeks later it was a phone interview with 2 people from 2 different departments. They asked me a lot of questions regarding my past experiences and some technical questions. All the questions were pretty straight forward and it went quite good. I was then invited to Berlin for a face to face interview. There i was interviewed by 4 people from 3 different departments. They asked me a lot of questions both technical and non technical they asked management related questions and what decisions I would take in certain situations. The questions were not technical hard stuff they were very opinion oriented and did not have a correct or wrong answer rather i had to give my opinion. Eg. what will i do to convince the managers to accept a idea. The bad part is that its been 2 months and I have not yet received a reply on my application. I emailed them yet no response.
