I applied online in august 2016. I first got an email inviting me to take a numerical and a verbal reasoning online. one week later i was called by a HR, 30 minutes call, she described the interview process and invited me to attend a case interview preparation webinar. one week after i had my first case interview (PEI + case)

Phone screening interview, followed by 5 rounds of case interviews. Was initially slated to be 4 rounds of case interviews, 2 guaranteed, 2 provisional. I was offered a third one after the first two to confirm if they wanted to move forward with me. Each interview was with an increasingly senior employee with the final being the partner.
