Interview
There were 2 steps in the onterview process. The interview was held at OCR in NYU. They asked me simple questions like what is time series and data exploration and what i s the formula for linear regression. They asked me three questions on probability
First round was a case interview and final round was a behavioral interview with a more senior member of the team. Each interview was 45 minutes with one member from the team.
There was only 1 round of interview. Heard from recruiter 1 month after submitted application. Interview was 1 hour and did not seem structured at all; it went over a mix of technical and behavioral topics.
First stage of CV application, followed by an in-person assessment centre, then final interview with hiring manager in person in Southbank London office. Many assessment centres were running throughout 2017 when i applied.
