To sum it up: I don't give a rats ass for any degrees. I don't even have one myself. We send applicants a programming test. I get these tests, and I assess them without even skimming the CV. Because it would otherwise just skew my observations.
If the test convinced me that you can code, you will have a job-interview, via phone or in person depending on if it's feasible to fly you in to Berlin or not.
This interview is pure technical, either.
If this convinced me that you are a good coder, I will arrange a third interview with the CTO, who has the final say on all employments. I won't spoil the enjoyment of that for you :)
