Qatar Petroleum Senior Electrical Engineer interview questions

I was contacted by an excellent and very professional HR company, I have to say, in 2016. QP was building accommodation/offices. Although the agency did a great job, everything after them and directly dealing with QP was a mess. I wa scheduled an interview 5:30AM London time. The interview was a phone call with 2 very strange Eastern characters. Weird questions, some making fun of me and my career (I have no idea why). Ended up with me going to work tired and forever regretting I ever wanted to join and work with such people.
