What does the O2 Ireland data scientist interview cover?
Expect a mix of applied ML/statistics, an experimentation or metrics round, a coding/SQL screen, and a behavioural round. O2 Ireland cares about whether you can frame a fuzzy business problem as a tractable modelling problem.
Do I need deep theory for the O2 Ireland DS interview?
You should understand the fundamentals (bias/variance, regularisation, experiment design) but most rounds reward practical judgment: choosing the right approach, validating it honestly, and reasoning about real-world failure modes.
How important is communication for a O2 Ireland data scientist?
Very. O2 Ireland assesses whether you can explain a model and its limitations to product and business stakeholders. Practising that narrative on camera helps you present complex work simply.
