J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez Deliveroo (Londres, Angleterre) en mars 2019
Entretien
Initial relaxed phone call with their technical recruiter. Followed by two video interviews. Then an afternoon of 4 face to face interviews with members of the different teams a Data Scientist commonly interacts with . These interviews were back to back with a break in the middle with the recruiter.
The interview types were:
- 2 Career History
- 2 Behavioural/Cultural Fit
- 2 Experimentation/Technical
The Experimentation/Technical interviews focussed on my experience of running experimentation, the statistical considerations you make when setting up experiments and examples of data analysis I have completed that led to an action.

Question 1
Tell me about an experiment/analysis you’ve complete from start to finish. What steps were involved and how were the results were communicated to stakeholders?

Question 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.
