I've a PhD in pure math, with postdoctoral experience in theoretical/statistical aspects of machine learning, with over seven years of teaching experience in math in English, and currently a part time lecturer of math in an engineering school in France. This year I applied to 44 full time MCF positions (assistant professor) in France, and all the places that I thought had something to do with my research, didn't call me even for an audition. However, only a French engineering school specialized in mechanical engineering called me to audition - to my (somewhat pleasant) surprise. For reference, MCF comes with mixed teaching and research responsibilities.
I had applied to this school of engineering (this is one of the "Ecole Supérieures") in the CNU Section 26, just to take a chance. I also communicated with the people in charge and specified that my French was only intermediate and they replied by saying that nearly 100% of the teaching would be in French, and thus not being able to provide the lectures in French will be a unfavorable point of any application. I cannot obviously ask the school why they selected me, because that'd obviously negatively affect my application.
I looked the faculty research interests, that got nothing to do with mine, and on top of that the language would be a barrier at this point (not that I don't want to improve my French, but I'm just not there at this point...).
So my question is: why am I being called for an audition? I'd hazard a guess that they didn't get a lot of applications OR that they're planning to give me a lot of teaching load, having seen my teaching experience; both would be a point of serious concern, considering my professional goals and my passions related to it - which is research in theoretical machine learning, and not a lot of teaching (no more than 200 hours a year). I emailed the selection committee asking if I could audition in English, and the answer was no. Also, anyone looking at my CV would figure out that I'm not a statistician (although I do know a fair bit), and yet they asked me to present a teaching demo of inferential statistics, something where I've not published nor taught in a classroom setting!!! So I don't understand why the school is trying to have it their way and yet asking me for audition - seems genuinely confusing to me. I can't obviously ask the school why they selected me to audition, as that'd negatively affect my application (although in case, I'm certain that I'd not be offered this position anyway, perhaps for the better).
I'd appreciate responses, especially from people who were in the same situations so that I know how some assistant professor selection process goes - this is one of my goals to know, or those familiar with French higher academic system. Thank you in advance!
