I mostly see job ads whit the title "Junior Software Developer (m/w)". I speak German and thus the thing between the brackets stands for "male"/"female". I don't know whether this also applies to other countries but in Germany at least this is absolutely the common case.
Why is this done? I mean it's not like someone would be surprised that a software developer can be female or male (in fact it's even illegal to exclude a specific gender from the hiring process).
