Applied through their careers platform for a Summer Internship in Technology in London. Got a phone interview two weeks later. The interview lasted for 40 minutes, but was mostly technical. You might get asked why technology and that's it, the interviewer will jump right into technical questions. The monotone interviewer felt slightly hostile. Be prepared to be asked detailed questions about a programming language you mentioned on the CV and eventually some concepts you might not be familiar with, so make sure you do some reading beforehand and take a look at some of the questions below.
