So I've recently compiled 3 UX case studies done in classroom on my portfolio website and when asked to present a case study during interview I showcase one case study in the form of presentation slides. But the issue is that the interviewers somehow don't like the process that I have utilised as I think it seems very linear: Secondary research, primary research, contextual inquiry, surveys, competitor analysis, SWOT analysis, ideation, solution sketching, etc. I hope you get how linear this process is.
So I've created the project with it's UI design and have tested with the users. But still somehow it feels like I chose the wrong audience for giving the solution.
So do I start the project again from scratch or now that I have made the UI for a particular audience, I improve it for them?
(Please suggest some tips on improving the UX process as well)
Also I did these projects within a timeline of a month. So how do I optimise to take much lesser time than that for redesign?
