I applied online. The process took 6 weeks. I interviewed at Linköping University in Jul 2013
Interview
It ws a skype interview where I we discussed numerous of questions that related to materials science and nanotechnology. The interview duration was near 1 hour. I do believe the group lead was satisfied with my answers. In the same time I was satisfied with the answers of the group lead.
I got a mail in advance for scheduling the skype interview. I had a good time explaining myself and my project. Later, I got the decision. I got paperwork done quckly to apply for visa. But, my visa got delayed due to the embassy problems.
