He doesn't mean a recruitment interview but one about him for the Fog Creek blog.
If the poster actually wanted to avoid that ambiguity, a better title would be "I was interviewed by the Fog Creek blog," or "Peteris Krumins' interview on the Fog Creek blog"
My first impression of the title was that somebody interviewed for a job at Fog Creek, but the process was so impersonal that he or she had to put "I" in quotes.
