+# Preparation for second round Interview for grant to do PhD in Paris
+
+length: 10minutes + 10minutes questions
+
+## Outline
+ 1. Airshowers / Ultra high energy / Radio Signal
+
+ 2. Radio Interferometry principle
+
+ 3. RI requires good timing -> work in internship
+	mention, but put most in [backup slides]
+
+ 4. Direct Advantages of RI
+	(follow airshower through the air)
+
+ 5. RI, CRs and Neutrinos
+	(better direction reconstruction is interesting for Ns not for CR)
