I previously quit a STEM PhD program after 1 year. The reasons were complex but included burnout, mental health, pressure from the industrial sponsor, lack of support and loss of interest in the project.
Following some time out of education, I decided to reapply for PhDs. I have been invited to interview for a very competitive PhD program. It is stated in my application that I started a PhD previously, and I expect to be asked about this in the interview.
The answer is messy and difficult to talk about - how can I explain it in the best light possible?
