Capgemini Invent Senior Consultant - Data Analytics interview questions

Had a video interview and was shortlisted to go for the final round - final round consist of a half day 5hour back to back session testing your consulting skills etc. Weirdest thing was that they never got back to me or even update me that I didn't get through the process, after investing so much of my time in the interview process. Would've appreciated an update at least. Highly unprofessional.
