Few days after I have submitted my application I received an email letting me choose the hour I would like to have the phone interview. The interviewer called on time and started by explaining me the detail of the next stage if I pass. I started using the headphone which help me to hear him better but he found trouble to hear me, so I use the mobile phone directly which caused me a little difficult. I had to ask him to repeat question because the connection. The interview questions were all about what I knew about the company, why I want to for them, what they did in this industry recently and some behaviour questions like my teamwork experience. There was a tough question about how many windows in Buckingham Palace, which I found unexpected at this stage and struggled to answer it.
