J'ai postulé en ligne. Le processus a pris 2 mois. J'ai passé un entretien chez Tesco (Londres, Angleterre) en janv. 2022
Entretien
There are 4 main steps:
- chat with recruiter
- interview with 2 data scientist (easy live coding challenge about sorting + theory questions on Machine Learning)
- take home assessment with 2 tasks: normalized sales predictions + regression on an anonymised dataset
I only got to the 3rd stage as they ghosted on me after the submission of the assessment (after one month still nothing). Very unprofessional and disrespectful.

All the interviewers and the talent acquisition partners were friendly and pleasant to interview with and made a long process easy to handle!

Quite simple if you prep for it; 2 interviews first that you don't need to prep for, followed by an assessment that you should not overthink given they give you 1 week (just stick to the basics). Final stage involves 3 interviews with senior staff and managers
