BAE Systems Process Engineer interview questions

I was contacted by 3 different recruiters for 2 roles within the Engineering function at Warton. I was told by the recruiters that they wanted to interview me, though they didn't have a date for me at that time. I then received an email inviting me to interview for one of the roles, both interviewers had been told the interview was for their role. After some digging, they found that the interview was for both roles, and the interview pannel would be made up of the two hiring managers. Come the interview, only one hiring manager was there and he knew nothing about the other role. The interview was also late to start because their HR representative was having issues with their outdated Webex video conferencing system. I had prepared to be interviewed for both roles and was thrown when it was just for one, so I was rejected for the role, and have since heard nothing about the other. Likely dodged a bullet given the disorganisation throughout the hiring process.
