Hi
@conquering-house Work experience before applying isn't necessary, no university will reject an application because of a lack of relevant experience, especially as it is so hard to get lab-based experience as an under 18. However, work experience during university is really important.
I did a placement year in biotechnology (early drug discovery and development) as part of my degree, this role was advertised by the company on their website. I also applied for a research internship at my university which was advertised by a dementia research charity based at Lancaster University, however, my department also advertised other summer internship opportunities.
I think work experience is really important. It can help you understand what it's actually like to work in a lab (I experienced both an academic and industry lab, which are very different) and if you actually like working in science and want to pursue it after graduation. You can learn new scientific techniques and contextualise the content you've learnt at university. Additionally, it can make you much more competitive when applying for graduate roles or further study.
With how the job market is right now, I think getting any work experience during university is essential, even if it's part-time or unrelated to your degree.
Best of luck with finding an opportunity, please let me know if I can help you with any other questions.
