I met with the professor yesterday and a post-doc with which I will have the closest relationship. My impression was good, although they seemed very worried about the case I declined and they would need to find another candidate. Furthermore I asked two previous PhD students of theirs which are not at this university anymore and they both spoke in high regard for both the professor and the post-doc. I can also tell that their research is top. As mentioned in my post I would like to be able to work remotely in the future. Having a remote position is to me even more important compared to doing research (although a combination of those two would be ideal). I am worried about whether doing a PhD can prohibit me from achieving that, since I will be gaining a lot of research experience but I will lack programming experience (especially commercial programming experience). Am I overthinking it?
