Imperial Molecular Bioengineering Personal Statement

Hi, I just wanted to ask what types of things people have included in their personal statement for the molecular bioengineering course for imperial in the past and whether these can have a lot of overlap with biochemistry. At think at this moment I am thinking about a career in biotech, and because the course at imperial is such a niche course, at this moment in time I'm likely to apply for biochemistry at most of my other options.
