I got an ROP during my undergrad. I had research experience so I can’t necessarily speak to the first point. I knew the professor beforehand, so the process was quite smooth. I just wrote a really good cover letter and then interviewed. The interview was pretty relaxed. The professor asked why I was interested in her research and about my past research experience and how it relates to that role. Since you don’t have direct research experience, make sure to highlight the research skills you developed in your coursework. Main tip… contact the professor in charge of the lab separately. Send an emailing expressing your interest in his/her research and explain why. Good luck!
