3 rounds and technical assessment. First interview: coding exercise, technical questions. One week to do assignment then interview to discuss solutions and another one on more in depth technical knowledge.
Interview questions [1]
Question 1
Bias-variance trade off, regularisation, model comparison.
I applied online. The process took 2 months. I interviewed at Tesco (Londres, Inglaterra) in Jan 2022
Interview
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.
