I applied online. The process took 2 weeks. I interviewed at ION Group (Pisa) in Apr 2024
Interview
After CV screening, chat with the CTO, then a hacker rank test and a final interview with some live data science and coding tests.
Overall, not so complicated. However, they sell as data science what actually is a lot of data cleaning and analysis, modelling does not go further than a logistic regression.
Indeed, the live coding test was full of "gotcha" on data quality issues, Zero interest in assessing modeling knowledge.
