IBM User Experience Design interview questions

interview 1) 60 minute portfolio review of one project case study and then interview 2) presentation of a 4-6 hour take home design challenge. For the second interview, we were told to spend 4-6 hours on a heuristic review and designing solutions and creating mockups of these screens

There were multiple online assessments and 1 take-home design challenge. The challenge was meant to be completed within a certain amount of time (I think it was 2 to 4 hours or so).
