You're going for a Data Scientist role.
And we're rooting for you.
But does your experience match the job?
Here's what the role really asks for, and a clear way to see where you stand before you apply.
The core of the role
Four things a Data Scientist is really hired to do.
Most Data Scientist “skills” lists are just a pile of algorithms and libraries. These are grouped the way the work actually happens, from turning a fuzzy business question into a problem you can model, to handing back a decision someone can act on.
Frame the problem
Before any model, you turn a vague business question into something measurable, with a target and a way to tell if you've succeeded.
Get the data honest and usable
Most of the job is here: pulling data together, cleaning it, and shaping features without quietly leaking the answer into them.
Model, test, and validate
You fit models, but the real skill is knowing whether the result holds up, or whether you've just memorized the training set.
Turn a model into a decision
A model nobody trusts changes nothing. You explain what it says, how sure you are, and what to do about it.

Straight answers
Data Scientist questions people usually ask.
What skills do you need to be a Data Scientist?
Four things carry the role: framing a business question as a measurable problem, getting messy data into honest, usable shape, modeling and validating it so the result actually holds, and explaining what it means to people who won't read your notebook. The algorithms matter, but those four are what's really tested.
What's the difference between a Data Scientist and a Data Analyst?
Roughly: a Data Analyst explains what happened and reports it clearly; a Data Scientist builds models to predict or decide what to do next. The analyst leans on SQL and dashboards, the scientist adds statistics, machine learning, and experiment design. Plenty of jobs blur the two, so read the actual posting.
Do you need a PhD to be a Data Scientist?
For most roles, no. A PhD helps for research-heavy or specialised positions, but the majority of jobs care that you can frame a problem, model it honestly, and communicate the result. A portfolio of real, defensible work often speaks louder than the letters.
How do I show Data Scientist skills on my CV?
Lead with the decision your work changed, not the model you used. “Built a churn model” says little; “built a churn model that reprioritised retention spend and cut monthly churn by 1.2 points” shows the skill working. That's exactly what our scan helps you pull out of your own history.
