Interviewing at Waste Connections
Waste Connections interviews are built around practical, job-relevant tests, not just abstract discussions. Across the reported roles, you should expect SQL and Excel to show up, plus role-specific evaluation like sales experience for Sales roles and bookkeeping and financial work for Financial Analyst roles.
The topic distribution suggests the core screening signals are: SQL and Excel, sales experience for roles that sell, and accounting and financial foundations for Finance roles. You should also be ready for an applied, time-boxed case preparation element, and for showing analytical thinking, data organization, spreadsheet modeling, and interview communication.
Based on candidate reports, the difficulty is mostly easy to medium, with a small hard portion and no very hard cases. The reported offer rate is 0.0%, so treat the process as highly competitive or possibly unevenly measured in the dataset, and focus on performing strongly on the specific skills the interview topics prioritize.
The single most useful non-obvious fact is that SQL, Excel, and the ability to work in spreadsheets under time constraints appear among the top topics (SQL and Excel at percentile 100, plus overnight or time-boxed case preparation at percentile 83). Even if you are not a pure software candidate, your preparation should include spreadsheet modeling and structured data work.

What separates offers from rejections
Patterns from candidates who got offers, and the mistakes that most often sink a loop.
Do this
- Practice SQL tasks that fit real screening, since SQL is the top interview topic (percentile 100). Focus on writing correct queries and explaining your approach clearly.
- Be ready to demonstrate Excel skills and spreadsheet modeling, because Excel is also the top topic (percentile 100). Prepare to organize data, build a model, and interpret outputs.
- If you are interviewing for a Financial Analyst role, prepare for accounting fundamentals and bookkeeping topics, because they are highly prominent (accounting fundamentals percentile 87, bookkeeping percentile 95). Brush up on how you connect entries and statements to analysis.
- If a case is time-boxed or overnight, use a structured workflow: data organization first, then the analysis steps, then a short, direct explanation of results. Interview communication is a notable topic (percentile 70), so practice concise walkthroughs.
Avoid this
- Do not ignore sales background and motivation if you are interviewing for Account Executive, since sales experience is listed as a top technical topic (percentile 100). Keep your answers tied to outcomes and achievements.
- Do not treat the interview as purely theoretical. The process emphasizes analytical thinking, data organization and spreadsheet modeling, and time management (time management percentile 62).
- Do not rely on general behavioral answers alone. HR screening is present but less prominent (percentile 54), so your strongest material should still map to the technical topic priorities.
- Do not assume difficulty will be uniform across candidates. The dataset shows mostly easy and medium difficulty (easy 42.6%, medium 50.0%) with a smaller hard slice (7.4%), so you should aim for correctness and clarity rather than trying to guess how hard each component will be.
