Isogenica interview questions

I interviewed for a Senior Scientist position at Isogenica. The first round was the interview with two senior people. In the next stage, I was asked to visit onsite and deliver a 20 min presentation on a given topic of their interest. Very intense questioning and a lack of organisation. Directly followed by a technhical round with many people, Got constantly bombarded with questions which took around 30-40 min. Directly followed by interview with 5-6 team members for 45 min. In the end, had a meeting with CEO for 30 min. Some of the questions didn't make sense.
