Candidates who interviewed for Nokia's Data Analyst role describe a process that goes beyond SQL. One candidate began with a fit check covering aptitude, logical reasoning and verbal skills, then scenario-based coding questions, including swapping two numbers without a third variable. The other reports a coding assessment mixing data structures and logical reasoning, described as straightforward.
The technical content in one report was broad. That candidate was asked about ANOVA, statistical models, mean and variance, a Python matrix-operations question, SQL join types and when to use each, a C coding question, and a detailed explanation of Support Vector Machines, including trade-offs against other models. So it is worth reviewing statistics and core ML concepts, not only query writing.
The other candidate's process leaned on communication. After the first round came a take-home data analysis and visualization task, followed by a presentation where they had to defend their analytical choices. That candidate said the discussion focused on reasoning more than on getting a single right answer. Practice walking through your findings conversationally.
Both reports include behavioral conversations. Expect questions about your projects, the challenges you solved and where you see your career going. One candidate received an offer and the other did not move forward, so outcomes differ. Prepare project examples with specific metrics and a clear career narrative.

Real interview reports from people who went through the Nokia process.
The technical side was lighter than I expected. There were two technical rounds. The first checked that I had the basics, and the second went a bit deeper, though it still stayed on the straightforward end. Most of the questions were about SQL and dashboard creation, plus customer behaviour. I was asked about churn risk, how I would find high value audiences, and a few marketing analytics questions. Nothing was especially tricky, so I'd focus on being able to explain how you'd approach each problem clearly.
After the two technical rounds came a one hour round, followed by a general discussion with management. One question I remember clearly was why I wanted to join Nokia, so have a specific answer ready rather than a generic one.
I ended up declining the offer, so I can't speak to the rest of the process after that. The interview itself was good, though.
Prep tip from this candidate
The SQL and dashboard questions were described as straightforward, so spend your prep time on customer-level analysis, especially churn risk, identifying high value audiences, and marketing analytics scenarios. Also prepare a specific answer for why you want to join the company, since it comes up in the management discussion.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an opening screen that mixes aptitude and logical reasoning with straightforward coding. Reported questions included swapping two numbers without a third variable, and data structures questions described as simple. Clean, efficient logic appears to matter more than complexity.
One candidate reports separate technical rounds covering ANOVA, statistical models, mean and variance, a Python matrix question, SQL join types and their use cases, a C question, and a detailed Support Vector Machines discussion. Depth of understanding was reportedly tested, so expect follow-ups on why and when.
Another candidate reports a take-home assignment on data analysis and visualization, described as fairly straightforward, followed by a presentation round. There they explained their approach and findings and defended their choices. This stage may emphasize communication of reasoning over the final answer.
Candidates report behavioral and HR discussions about past projects, challenges solved, and where they see themselves in the future. One described follow-up questions on resume details. Prepare specific project examples with metrics and a clear career narrative, since these conversations were described as moving quickly.
