I wondered why this is.
I wondered why people are writing in English and not in German.
I asked myself whether the work will be carried out in English.
That would be something for me, at last conductive practice in my mother tongue and near home. What a treat, if only I had the time.
I have since enquired and both the advertisers below are looking for German speakers. I still do not know why the advertisements are in English, I forgot to ask.
