Visa interview: Will you return to your home country after your studies? Why almost all students answer 'Yes' to this question? Is this a must for student visa? I have applied to student visa from Iran to study master degree in Germany. I want to pursue PhD (may be in Germany or may be not) and I will apply to work for giant software companies after that.

I don't understand why people write this? 

[UPDATE]

I will immediately follow PhD after masters either in Germany or somewhere else. Also all students have 18 months job seeking visa extension. Then why should we lie? Embassy definitely knows that everyone will at least give himself a chance to work in a better company.

The host country is not looking to accept immigrants when allowing students to come pursue degrees on education visas.  Each country has their own system, standards and procedures for allowing immigrants in the country, and if you appear like you're trying to skip that by entering as a student they will deny your student visa application.
