I applied online. I interviewed at Ocado Technology (Hatfield, East of England, England) in Feb 2019
Interview
The interview process consisted of three stages:
Initial phone interview - general
Google hangout - technical with small python coding excercise
Assessment day - technical with applied data science excerices using python
My overall experience was positive. The hangout interview was conducted by two friendly senior team leads. We discussed the range of challenegs facing Ocado (e.g. demand forcasting, recommender systems, fraud detection) and how my skills can help in solving these challenges. I was also given a small python excercise and we worked together to arrive at the solution.
During the assessment day we toured the automated warehouse, which was impressive. I then sat with two other data scientist to solve a problem. The interviewers were knwoledgble and friendly.
