One at 11am by phone, then one at
I had agreed to both because the second one was in a suburb which was, I thought, close to the city centre.
A day or so after agreeing I looked at the map and found that the suburb was at the end of the S-bahn line.
Fortunately the telephone interview ended after 30 minutes so that gave me time to eat a banana and go out to the second one.
The first one was in English, the second in German. I explained that I can't maintain my German for over an hour and the interviewer said he'd consider it - his client is a very traditional German company.
