I have asked the person who was responsible for the application twice about the status of my application.
First time, he didn't read my email. After a week, I sent another email and this time he answered my email and told me they will send me an email shortly!
For two weeks, I didn't get any answer. I sent another email yesterday and wrote that I am "sacrificing" all other PhD positions for this position (this was really the case). It has taken over two and a half months after deadline.
Today, I have received an email from another person who is a secretary and he wrote me that my application is rejected, because of a close competition.
Do you think the fact that I have asked them several times and that in the last email I wrote "I am sacrificing ..." could have a bad effect on their decision?
