The interviewer alternates between short conceptual questions and small query exercises you talk through out loud.\n\nQuestions in this area, for example:\n\n**Statistics**\n- When is the median a better summary than the mean, and give a telecom example.\n- Explain a p-value to a non-statistician without saying \"probability of the null\".\n- You have KPI samples from two groups of cell sites; which test would you use to compare them and what assumptions are you making?\n\n**SQL**, on a table `alarms(site_id, severity, opened_at, closed_at)`:\n1. Sites that raised more than five `critical` alarms last month.\n2. Average time to close, per severity, for alarms that were actually closed.\n3. For each site, the most recent alarm (one row per site).\n\n## Example\nFor item 3 the expected answer is a window function (`ROW_NUMBER() OVER (PARTITION BY site_id ORDER BY opened_at DESC)`) filtered to row 1; a `GROUP BY` with `MAX(opened_at)` alone loses the other columns, and they will point that out.\n\n## What they look for\n- Comfortable, unhurried explanations of basic statistics; they care that you can reason about data, not recite formulas.\n- Correct handling of `NULL` in `closed_at`, date arithmetic and grouping.\n- Whether you ask about the size of the table before proposing a query, which signals real-world experience.",
      "follow_ups_md": "- How would you detect sites whose alarm rate is anomalous compared with their own history?\n- What changes in your queries if `alarms` has a billion rows?"
