How Tech Mahindra screens analysts

Analyst hiring at Tech Mahindra typically opens with an online assessment (quantitative aptitude, logical reasoning, verbal ability and a data-interpretation block), often with an English or communication module. That leads to a technical interview on SQL, Excel and analytical reasoning, and an HR round.

The company wants an analyst who can turn a business question into a query, verify the result, and explain it clearly to client stakeholders. Given Tech Mahindra's service focus, communication is weighted noticeably alongside technical skill.

SQL, Excel and statistics

SQL is the core. Practise JOINs, GROUP BY with HAVING, subqueries, and window functions (ROW_NUMBER, RANK, LAG/LEAD, running totals). Common ask: top N customers by revenue per region, or month-on-month change in a KPI. Narrate your logic as you write. Most Tech Mahindra Data Analyst / Data Science Jobs at this level assume fluency in exactly the SQL and case-reasoning patterns above, so drilling them pays off directly.

Excel: VLOOKUP/INDEX-MATCH, pivot tables, SUMIFS/COUNTIFS, and cleaning a messy dataset.

Statistics: mean versus median, percentiles, correlation versus causation, and outlier handling. You may interpret a chart or explain a sudden metric change.

  • Strong: confirms the grain of the data, states an assumption, flags a limitation, and explains it in plain words.
  • Weak: queries without checking what a row means, or explains it in jargon a client could not follow.

The case and HR round

Expect a light case: a scenario such as declining usage or rising complaints, and how you would investigate. Structure it, frame the question, list the data, choose a metric, segment, consider confounders. A logical approach beats a memorised template.

Your projects come up: narrate a dashboard you built (Power BI, Tableau or Excel), the decision it drove, and one surprising insight, in accessible language.

The HR round covers why Tech Mahindra, relocation, shift flexibility, and behavioural stories. Prepare a two-minute introduction and one example of explaining a technical finding to a non-technical audience, precisely the communication strength the company looks for.
