5 interviews of 1-hour each including a 20 minutes presentation with a PowerPoint that I had to make, spread across 2 months. Don't make the mistake I did, don't apply, they will only make you lose your time. Besides that, the communication was horrendous, they never let me know about what the next steps were, with who etc. and that is because they don't even know it themselves, pathetic. Finally, during the last interview I had to give a 20 minutes presentation which went well, but there were 5 people on the call including 2 seniors, and not one of them knew who was the facilitator of the interview. Senior people who are not organised? Really, don't apply
