this was for after the spring insight for the summer internship, there was a set of two rounds of interviews. both relaxed at the beginning where they get to know you first, then proceed to ask you questions about the position etc. then case studies presented where you had to work them through how you solve them etc

Three question long HireVue online interview. Were given access to practise questions but these were a very different style of question to those actually asked. However the questions themselves were reasonable and were mostly about your understanding of the company themselves.
