Interviewing at Culligan
Culligan interviews are a mix of recruiter and HR screening plus multiple technical and applied discussions. Across the reported steps, you should expect both leadership and stakeholder-oriented questions, and you should be ready to go deep on data work such as SQL, ETL, pricing, and analytics case studies.
What the loop tests is heavily role-dependent but consistent in pattern: analytical problem solving shows up at the soft skills and leadership level (percentile 48), stakeholder management shows up as a technical skills theme (percentile 41), and the technical core is dominated by SQL (percentile 100) plus applied business analytics topics. For the data-heavy roles, topics include ETL processes (percentile 96), business analytics and data analysis (percentile 93), and analytics case studies (percentile 96). For commercial and finance adjacent roles, pricing strategy and optimization (percentile 100), pricing model governance (percentile 94), financial analysis for FP&A (percentile 97), and commercial sales strategy and vertical or residential selling (each percentile 100 or 96 and 93 respectively) are prominent.
In terms of how the process unfolds, the reported steps include initial screening touchpoints, then deep-dive style conversations and final interviews, with optional group orientation and shadowing. From candidate reports, difficulty skews medium (53%), with fewer hard and very hard questions (9% and 1%). The offer rate in the aggregated candidate reports is 0.0%, so focus on doing well in each stage rather than expecting fast closure.
SQL and pricing or analytics case work are the most consistently prominent technical topics, with SQL at the top percentile (100) and analytics case studies also highly prominent (96), so you should prioritize being able to explain your thinking and results, not just the final answer.

Do this
- Prepare to use SQL to answer business questions, and be ready to walk through your approach and reasoning, since SQL is the highest percentile topic (100) and stakeholder management (41) and analytical problem solving (48) are also tested.
- Rehearse an end to end analytics story: data preparation, transformation, and the business conclusion. ETL processes (96) and business analytics and data analysis (93) appear as technical topics, and analytics case studies (96) are also prominent.
- If the role touches pricing or finance, practice structuring your answer around pricing strategy and optimization (100), pricing model governance (94), and financial analysis for FP&A (97).
- Be ready for leadership and cross stakeholder conversation. Analytical problem solving (48) includes soft skills and leadership, and stakeholder management (41) suggests you should clearly explain tradeoffs and who the output is for.
Avoid this
- Do not treat interviews as purely technical. Analytical problem solving includes soft skills and leadership (48), and stakeholder management is explicitly present (41), so purely technical answers may feel incomplete.
- Avoid focusing on only one topic area. The interview topics list is broad and includes SQL (100), ETL (96), analytics case studies (96), and commercial or pricing topics (multiple at 94 to 100).
- Do not assume the process is short or linear. The reported steps include multiple screening and interview types, and some candidates may also have group orientation or shadowing.
- Do not over-rely on difficulty level expectations. Even though medium questions dominate (53%), there are still hard (9%) and very hard (1%) items, so you should prepare for at least one challenging technical or case style discussion.
