I applied online. The process took 2/3 weeks then I interviewed at UNStudio.
The interview was done over skype, it was very smooth . The interview was very professional but friendly. We talked about my previous experience, softwares, and I was asked to present a couple of projects from my portfolio. The interviewer also explained the kind of projects the firm was working on, the project that I'll probably be involved and the overall design process and presentation of the office.
