Delta Executive Search interview questions

Met the business development officer for interview. Very outdated views - told me off for having a beard and asked personal questions regarding family and why I don't want to live in the Middle East. Mentions halfway through the interview that internship is unpaid and there was no mention of this in job advertisement. Complete waste of time. Got the feeling it's an old-fashioned and conservative firm and rejected them straightaway.

Applied on the company website. Interviewed in London office with Business Development Manager. The interview was easy. Behavioural questions in general. The interview took about 30 minutes. They called me back on the following day.
