Thank you Caro!
Well, I contacted the Supervisor once, and that was before applying, to ask if I am eligible. And I did not send him a thank-you email, I did not want it to be understood as a desperate call.
I am going to follow your advise, and perhaps send an e-mail by Monday, as they precisely said: We have few candidates to interview, and some paper-work to do, and we'll get back to you next week.
Any tips of how to distract myself from feeling anxious? :)
Thanks again!
Moula
