我觉得四大的经历比较单一,but it depends how you explore your experience and convey such information to the admission officer.
changing a job, such as consulting etc, could diversify your knowledge and give you the edge, but it also depends on how this job make you professional mature and level you up in your career development path.
So i will say get yourself prepared, and shoot confidently.
even though you fail, you grow in this process, that is what i think about the application thing.
