Thank you Guys for your suggestions!
I'll be 28 year old on the next 8th of June and I graduated (BSc) in Biology in 2011 in Italy. After that I spent one year in New Zealand, working and living there, since I decided to come back in Italy to get a MSc in Reproductive Biotechnologies. I concluded my MSc last October and I have been already working in three different IVF labs for one year. I thought that maybe many PhD positions are already assigned and Uni's advertise them just because they have to. This should be a shame! Many of them just replied: "In view of the large number of applications (1000+) we regret to inform you that we are unable to pursue your application further." Could this be a serious motivation to be excluded?!?!?! For me it has no scientifical evidence...

Dear Collegues,

in the last 5 months I have applied to many PhD programmes (most of them in Germany) following scrupulously the procedures indicated on their website. I graduated (MSc) with 110/110 Magna cum Laude, I have 2 pubblications (one of them as 1st Author) and I have two referees who are available to support my application.
Despite those requirements, I have not been accepted from all the PhD (around 12) I have applied for ( also without have performed the interview!).
Is this normal? Should I continue to try with further applications or should I give up? I feel like an incompetent...
