FTDI Engineer interview questions

The written test was a standard one, testing the basics. The technical Q & A was strange.One of the interviewers asked about the age of the employee.Why didn't you do a Master's Degree ? If this position demanded a Mater's degree, why did they shortlist my profile ? One of the interviewer was too nosy in knowing the personal details of the employee. All in all, it looked like they humiliate interview candidates, by asking irrelevant questions.
