Freelancer Software Developer interview questions

For reference I was studying my master in InfoSecurity when I accepted to join Freelancer. After being contacted via Linkedin by the director of people and talent at Freelancer, Joe Griston, we had a chat about the company and myself, what I had done and what I wanted to do etc. Following the phone call we agreed on a date in which to come into the office for an interview. The interview involved meeting London's project manager and an engineering team lead, we talked for a while and then an exam of sorts, basically to find out what you know and how you figure out problems. The questions were not difficult but they were varied. After the test the engineering team lead went through the questions with me, discussing them as we went. The next day I got a call with an offer and I gladly accepted as the team seemed like people you would love to work with, and they are. #teamlondon!

This is only the first interview, I had a question sheet with 8 questions, they gave me an hour to do it. When I finished, 2 technicians came to speak with me, mainly about how I attempted the questions and how to improve.
