In case there is someone interested, I have started writing a blog about my last months of PhD and the transition to a job outside academia. I still didn't have time to write many posts or furnish it, but I will do these things once I have a bit more time :-)

It is just my personal experience. Therefore, I do not intend to write a career guide or anything of the sort. I hope it's useful for all those who would like to hear from someone who is currently trying to make the transition.
