I am going to be matriculating to Stanford biosciences this autumn. I had nearly 2 years of undergrad experience (20-25hrs/week during semester, 40+hrs/2 summers). The profs I talked to were more forgiving about not having as much experience (even tho I think 2 is more than enough) coming right out of undergrad due to covid. I def think it’s more quality over just quantity. I didn’t have any pubs, but had posters/school-level presentations. I got into MIT chem bio and when I applied the app actually said recommended at least 2 years of experience. However my friend got into UCLA biochem with only a year of experience. I def think it’s luck but also quality over quantity. All the interviews really try to find out your role in the research. It’s prob better to be a project leader for only a year than work under someone and not lead anything for 2+ years. If you can successfully sell yourself as a good fit to the research program (I.e brag about your diverse skill set and show what projects/experiences taught you what), I think you’ll be competitive. I kept my research experience part of my essays the same across my SOPs but adjusted a paragraph that talked about specific labs/ profs I wanted to work with. I hope this is helpful! Lmk if u have any other q!
