1 phone screening for 30 minutes with the head of corp dev. Then 5-6 back to back interviews on video or in person. The people that interview you are those that you will potentially work with over the role. It also includes two HR interviews. I interviewed with marketing, business strategy among other functions even though I was gunning for corporate M&A. The goal is to know the company extremely well so do your research. The people are extremely friendly and questions are not difficult if you do your homework.
