Let me check for a few more specific quality issues: 1) Check if there are any jobs with posting_date after application_deadline (logically impossible), 2) Look for any anomalies in the relationship between experience_level codes and years_experience ranges, and 3) Check if salary values are consistent with their currency (no obvious unit mixing). I'll start by checking for temporal inconsistencies.",
