Initial phone interview which was an informal chat for about 40 minutes. The second stage was a 3.5 hour interview. This feels extensive but it goes quickly and is the final stage of the process. For this role it includes a technical test where you are given an hour to read through a software development problem/scenario and construct your answer. Depending on the type of role, this could be a practical coding test or a whiteboard walk through of your answer. The walk through forms the basis of the main part of the interview. It's an open forum Q&A, typical of a competency based interview but drawing on your answers to the technical test as well. Using this method means you can tailor the interview to show what your strengths are and where you want the interview to go. They were looking for lots of types of people so were flexible on what they were after. Part way through, there is an opportunity to speak to a senior manger and some more questions on background and what makes you good at the job.
