I am a 31 year old international student. I applied for a PhD position in one of the top Australian universities. I’ll interview by Skype next week. I have a three year gap between my Master's and this PhD position. During these three years, I applied to many universities but was rejected from all. My GPAs are both above 3.8/4.0. I don’t want to work on something related to my master project.
I don't have any article yet. I wrote one three years ago but my supervisor, who is the corresponding author, submitted it only this April. Because I need her recommendation I couldn’t do anything but politely request to submit it.
In these three years, I took the GRE and IELTS exams (the latter was expired two weeks ago). I wrote a review article which I don't think my supervisor will ever try to submit. I tried to learn Python and R programming although I can’t say I am good. I participated in the translation of a book related to my major. I am also a high school teacher of 11 years.
Australian universities care so much about articles and research background which I don’t have. I don't know what I should say about this three year gap. I love research but I live in a small town in a deprived area of my developing country and I didn’t have any chance to participate in research. I also have a commitment with the educational office to work at my home town, that’s why I didn’t leave here. (During my studies I traveled around 2000 km every week to attend the university at the capital city of my country). However, now that I think about it I at least could have learn some bioinformatics tools and write an article.
How can I explain my gap without research? I don't want them to think that I make excuses. I love the project and I don’t want to lose this opportunity.
