It was one of the most delightful interviews i have had. i initially talked with the HR at Birmingham, the I had a second phone call interview with the managing director of the department in London, where we discussed over multiple issues and trends in the Data Market. I felt really nice throughout the process. Good questions, focused on my interests , studies and what i have been doing jobwise.
We also discussed over their models and process of data analysis as I was previously working at a research center extracting polls, and i had questions on the structure of their algorithms.
The final stage was a three hour interview with a 90 minute assesment and competence test.
