This question already has an answer here:
I applied for a research position at a University abroad and managed to go for an interview in person. The position I applied to was at Research Centre "A", but after some time, the prof emailed me suggesting that she would like to recommend me for another position at Research Centre "B" (he is the director of both centres).
He wants to arrange another interview with some of the researchers at centre "B", but honestly, I don't think I can afford making another trip down for an in-person interview, and I'm not even sure if i'll get the job. Do you think it's rude, and does it reduce my chances of making a good impression (or even getting hired), if I politely ask for a Skype interview instead?
I can't seem to find a reasonable excuse (other than expenses), so are there any other suggestions?
Thanks for your help!
