In-person interview - 30mins+60mins 30 mins - Prioritisation Exercise Question, 60 mins - Interview with Interviewers. In the invitation email, I was only told "You will be sent the exercise 30 minutes prior to the interview for you to prepare your thoughts on the given scenarios." then "walk though your answers and thoughts during the first 10 - 15 minutes of your interview following." I only presume it will be sent via email, but not told what I should use for the exercise (excel? notebook?...). nor did they mentioned dress-code, so I ended up over-dressed and over-prepare by bringing my laptop. which overkill the interaction.
