Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso Deliveroo (Londra, Inghilterra) nel mese di apr 2019
Colloquio
- The first interview was a phone call with the technical recruiter, who described the role and had a relaxed conversation about my CV and what I'm looking for. The recruiter also sent me some preparation material to prepare for the next round.
- Next one was two 30 minute interviews in the office with a PM and a Data Scientist. Mostly asked about my experience with Data Science and Experimentation.
- Final one included 4 interviews (Behavioural Interview, Product Interview , Stakeholder Interview, Business Case Interview). Again, the recruiter really helped me prepare for all of these and all the interviewers were friendly and made me feel very welcome.

Domanda 1
Why Deliveroo? and minimal unit of randomisation in A/B testing.
Straight forward process but very long and arduous with plenty of stages. I'd say it needs to be refined. Interviewers were very professional and rapport building was easy. I would suggest cutting down on the numerous steps in the interview
Very long process, 6 interviews and a take home task before being rejected. Brief of the task said don't overcomplicate it but the feedback I received was that I still didn't go into enough detail. So be prepared to spend a lot of time for the interviews. Generally friendly interviewers and easy interview questions, very straight forward standard a/b testing and causal inference questions. Despite this was rejected, would have brushed up on my domain knowledge in retrospect as I probably wasn't very clear answering causal inference questions to a product very different to my experience. The sql test was very easy and I completed all questions correctly, but got some negative feedback on this as I wasn't familiar with postgresql quirks around dates which they marked me down on.
