Preparation for an Accountant role at WM requires a balance of technical fluency and demonstrated reliability. You should be prepared to discuss your past experience in detail, as interviewers will look for evidence that you can handle the scale and pace of their operations.

Financial Accounting Competency

This is the core of your assessment. You must demonstrate a deep understanding of standard accounting practices and how they apply to the daily operations at WM.
