I had submitted a research paper to an IEEE conference recently. It's a new conference; the first occurrence of this conference. I submitted it, and did not receive a response from them even until a day after the day they said we'll receive our acceptance notification. So I called up the college that was organising the conference, and they said that my paper was not accepted, but I never received any results of the peer review process for the paper.
Before this paper, I had submitted one paper to an IEEE conference which was the 4th occurrence of that conference. My paper had two accepts, one reject, and finally the paper was rejected. But before that, I had received the comments of the peer reviewers. I know why that was rejected, made changes accordingly before submitting it along with some more results of my research to the 'first conference' I was talking about.
So my question is: Is it common to not receive the results of peer review (two of them according to their website), if the paper is rejected? Does it mean that my paper was desk-rejected due to something like incorrect formatting, or could it be because it's the first time they are organizing the conference so things are hectic for them?
One possible reason could be that I had first written the paper using LaTeX. Then I saw their website and realised that they required both a PDF and a Word file, so I copy-pasted everything from the Latex file to the Word file. As a result, a diagram went to the next page in Word and the text written after that diagram in the LaTeX file went to the previous page in the Word file. So there were slight differences in the formatting of the Word and PDF files, but does that reason make a paper incapable of even going to peer review?
For more context, I am a student pursuing B.E. in Computer Science and this paper was regarding my final year project.
PS: I am asking this just to get an idea whether it's a shortcoming on my part, so that I can correct it before submitting it the next time. My question here is about why I didn't receive the comments of the reviewers and not why the paper was rejected.
Apologies if these are too many questions, I would always be ready to split it or provide more information if required.
