I did the Spring Technology Insight Programme (five days) and was interviewed at the end of it. Presumably, ongoing evaluation was happening throughout five days. The interview itself was two parts - about an hour each with two people: one asked questions about my technology abilities, one about general competence.

It was a very smooth process arranged by the campus recruiter, first round was video interview and code vue, followed by a two hour individual last stage interview that included both behavioural and technical questions.
