Entretien
Applied online and about a month and a half later heard back about wanting to speak more about my application. First interview was over the phone and not so formal - got to learn about the position and company a little more. Second interview was more formal - was asked to talk about myself and my related experience; strengths, weaknesses; other typical interview questions. Got offered the position within the same week.
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.
