First had to complete phone interview with the hiring manager where we spoke mainly about my past experience, with some competency questions, then a written assessment where I had to respond to a customer request for memorandum, then 5 1 hour long interviews over 1 day. One of the things I was told by the recruiter talk about data points to act as evidence as much as I can, but I struggled with this at times as my examples were bid related, and I couldn't get in numbers as evidence, only general feedback that I've been given, which seemed to not go down well.
Also, I was told to use the STAR method, and I think at times I didn't because of nerves. If I did it again, I would follow this for every question to stop me waffling.
