JPMorganChase Machine Learning Software Engineer interview questions

Applied on the company website, about a week later I was called and asked to do an initial interview. This first one was around 45 minutes and mainly went over my resume and past projects on that. Then was called to schedule a technical interview that was 30 minutes long. This covered on conceptual question about AWS and setting up an ML pipeline and then one coding problem. The recruiter did not explain what this job listing was for, and the specifics of it, or what the interview process looked like. This left me unable to actually prepare for the effectively for the interview. Just poor experience overall.
