CGI UX Designer interview questions

Applied via CGI portal. Got a call from HR who scheduled Design interview. Interview went really well. They provided a design assignment which was huge. Assignment requirements - User research, persona, user flows, user journey map, wireframes. Basically entire case study in 2 days. Still I completed and got a call back. Managerial interview was scheduled which was quite easy. Offer letter was rolled out immediately after that. Whole process took 15-16 days.
