Apply online through workable I was contacted 2 months after for taking a data analysis assessment. Final interview with three Economists. Make presentation with few slides to explain results of the data assessment. 2 weeks after 2 weeks I got the outcome. If you never work on UK project they will not hire you even if you have the skills.

Two interview rounds. The first interview was more about getting know each other, interests, the team. The second interview was with more senior staff members, a bit more on talking about technical abilities and interests, followed by a case study writing assignment. The assignment took 2.5h and was adequate for the level that I applied for. The process took a long time. Sometimes I did not hear anything for several weeks and had to chase them, other times they were super responsive and called me spontaneously to discuss expectations. Overall positive and friendly, but at times inconsistent!

Panel interview with multiple people. Lasted two hours. Panelists were nice and professional. Described the position, asked a series of about 10 questions, asked about interest in topical area of project and technical skills.
