Candidates describe Nielsen's Data Analyst interviews as a mix of practical technical screening and business judgment. One candidate reports a three-part process: SQL and Python questions, a business case, then a conversation with the potential manager. The technical portion included calculating average session time from page-load and exit timestamps. The business case asked what could explain a sharp sales drop in a product category and what to recommend.
Another candidate describes a faster, more technical path. It began with a 60-minute round covering machine learning and deep learning concepts, three SQL questions, and two Python challenges. The SQL covered Rank, Dense Rank and Row_Number, and one Python task was reversing a string several ways. That candidate then had a project walkthrough with a senior manager and a mixed technical and project interview with a Director, and reports the whole process took three days.
A senior analytics screen was more conversational. It covered fit with the job description, visa status, salary expectations, previous similar roles, and which sales KPIs the candidate would track and what they reveal. A separate analyst candidate reports an HR call, an interview with two interviewers, and then psychometric testing. Another reports an HR phone call and a face-to-face with the team leader, followed by a week-long silence after the interview.
All five reports here ended without an offer, so treat them as preparation signals, not as a fixed format. Practice window functions and timestamp-based SQL, be ready to walk through a project end to end, and rehearse explaining a finding to a non-technical manager. Have salary and visa answers ready, and ask about next steps and timing before you leave.

Featured question at Nielsen
In this problem, we are given two linked lists representing two non-negative integers, with each item in the list holding one digit. The digits are stored in reverse order, and each of their nodes contains a single digit. We are required to add the two numbers and return the sum as a linked list.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an initial call with a recruiter or HR contact covering experience, motivation for the role, and fit. One senior-level candidate was also asked about visa status and salary expectations, so it is sensible to have both ready before the call.
Two candidates describe practical SQL and Python questions. One involved computing average session time from timestamps; another covered Rank, Dense Rank, Row_Number, string reversal, and ML and deep learning concepts in a 60-minute round. The mix may vary by team.
One candidate was given a scenario where a product category's sales dropped and had to explain possible causes and recommendations. Another senior-level screen asked which sales KPIs they would track and what insights those would give. Expect to reason out loud.
Candidates report conversations with a potential manager, senior manager, Director, or team leader. Topics included walking through a built project, explaining findings to non-technical people, and technical follow-ups. One candidate also reports personal questions in the team leader round.
One candidate reports psychometric testing after a positive interview, and another reports no reply after a promised one-week decision. Another describes a three-day process. Timing seems to vary, so asking for a decision date and contact may help.
