01
Guesstimate: how many cups of tea are sold in Delhi per day?
Population about 20 million, adult tea drinkers about 50%, cups bought outside per person around 1 on average. This gives roughly 10 million cups, then adjust for offices and stalls.
02
What is the difference between Definition of Ready and Definition of Done?
Definition of Ready is a checklist a story must meet before the team pulls it into a sprint: clear description, acceptance criteria, dependencies identified, designs attached and estimated. Definition of Done is the checklist for calling work complete: coded, reviewed, tested, acceptance criteria passed, documented and deployable. The BA mostly drives readiness, while the whole team owns done. Both reduce rework and arguments at sprint end.
03
What is a spike in Agile and when would a business analyst request one?
A spike is a time-boxed story used for research or experimentation to reduce uncertainty, not to deliver a feature. Its output is knowledge, such as a recommendation or a prototype. A BA might request one when the team cannot estimate a story because an external API, a data source or a regulation is unclear, for example checking whether a payment gateway supports partial refunds. The time box, often one to three days, prevents open-ended investigation.
04
An order has a value of 600 rupees, product cost 360, delivery 60, payment fee 12 and a discount of 50. What is the contribution margin?
Net revenue after discount is 600 minus 50, which is 550 rupees. Variable costs are 360 plus 60 plus 12, totalling 432. Contribution margin is 550 minus 432, so 118 rupees per order, or about 21 percent of net revenue. This is what each order contributes towards fixed costs such as salaries and rent. If the discount were raised to 150, the order would contribute only 18 rupees.
05
How would you measure the success of a new feature?
Define a goal metric, a baseline and guardrail metrics, run an experiment or before-after comparison and review adoption, retention and revenue impact.
06
Write a SQL query to show cumulative revenue by month.
WITH monthly AS (
SELECT DATE_TRUNC('month', order_date) AS month,
SUM(amount) AS revenue
FROM orders
GROUP BY 1
)
SELECT month, revenue,
SUM(revenue) OVER (ORDER BY month) AS cumulative_revenue
FROM monthly
ORDER BY month;
-- add PARTITION BY EXTRACT(YEAR FROM month) to reset each year
07
Three departments describe the same order process in three different ways during workshops. How do you arrive at the true AS-IS?
Treat each version as a hypothesis. Walk the process physically or observe real cases end to end, and pull a sample of 20 to 30 recent orders from the system to trace what actually happened. Compare timestamps and status changes with each department's story. Then hold a joint session, show the evidence-based map and mark the variants openly. Often all three are partly right because different order types follow different paths, which should be modelled explicitly.
08
What are wireframes and why are they useful for a BA?
Check whether the extra sign-ups are lower-intent users who would naturally retain less. Compare Day-7 retention for comparable users in both versions and count retained users in absolute terms, not just rates. If the new flow skips a step that led users to the aha moment, retention per user may truly fall. The decision depends on whether total retained, valuable users went up or down.
11
How would you decide whether to launch a new product?
Assess market size and demand, customer need, competition, unit economics, capabilities, risks and strategic fit, then test with a pilot before scale-up.
12
After many sprints, project documentation is out of date and new team members are confused. What do you do?
Identify which documents are actually used: usually a product overview, process maps, business rules, data dictionary and integration details. Update those first rather than everything. Make documentation part of the Definition of Done, so a story is not complete until related docs are updated. Keep living documents in a shared wiki with owners and last-reviewed dates, and archive outdated files clearly. Test the result by having a new joiner use it during onboarding.
13
A stakeholder's only requirement is 'make the app faster'. How do you turn this into clear requirements?
Ask which screens or actions feel slow, for which users, on which devices and networks, and how it affects the business, such as checkout drop-off. Gather current timings from monitoring data. Then write measurable non-functional requirements, for example 'the search results page loads within 2 seconds for 95 percent of requests on a 4G connection'. Confirm targets with the stakeholder and agree how they will be tested.
ROI (return on investment) is the gain from a specific investment divided by its cost and is used to judge projects or campaigns. ROE (return on equity) is net profit divided by shareholders' equity and shows the return to owners; high debt can inflate it. ROCE (return on capital employed) is EBIT divided by equity plus long-term debt and shows how efficiently all long-term capital is used. ROCE is better for comparing companies with different debt levels.
Situation: a new city launch was 30 percent below its order target after two months. Task: present the review to the leadership team. Action: I opened with the number directly, then broke the gap into traffic, conversion and repeat rate, showing repeat rate was the main problem. I came with three options with estimated impact and cost. Result: leadership approved a focused retention campaign instead of more ad spend, and repeat rate rose over the next quarter.
17
What is the difference between sequence flow and message flow in BPMN?
A sequence flow is a solid arrow that shows the order of activities inside one pool, so it represents work controlled by one participant. A message flow is a dashed arrow with an open circle at its start and shows communication between two different pools, such as an order email from a customer to a seller. A common modelling mistake is drawing sequence flows across pools, which wrongly implies one party controls the other's work.
18
Write a SQL query for Day-7 retention by weekly sign-up cohort.
WITH cohort AS (
SELECT user_id, signup_date,
DATE_TRUNC('week', signup_date) AS cohort_week
FROM users
),
ret AS (
SELECT DISTINCT c.user_id
FROM cohort c
JOIN events e ON e.user_id = c.user_id
AND e.event_date = c.signup_date + INTERVAL '7 day'
)
SELECT c.cohort_week, COUNT(*) AS users,
ROUND(100.0 * COUNT(r.user_id) / COUNT(*), 1) AS d7_retention_pct
FROM cohort c
LEFT JOIN ret r ON r.user_id = c.user_id
GROUP BY c.cohort_week
ORDER BY c.cohort_week;
19
Write a DAX measure that shows each category's percent share of total sales.
WITH ranked AS (
SELECT category, product_id, SUM(amount) AS revenue,
DENSE_RANK() OVER (PARTITION BY category
ORDER BY SUM(amount) DESC) AS rk
FROM sales
GROUP BY category, product_id
)
SELECT category, product_id, revenue
FROM ranked
WHERE rk <= 3
ORDER BY category, rk;
Power Query is the data preparation engine inside Power BI and Excel. It connects to sources like Excel, CSV, SQL databases and web APIs, then lets you clean and shape data with recorded steps: remove columns, change types, split, merge, unpivot, append and group. Each step is written in the M language and replays on every refresh, so a monthly cleanup job becomes repeatable instead of manual.
22
How is a product owner's role different from a business analyst's role?
The product owner owns the product vision and the backlog order, makes final priority decisions and accepts completed work on behalf of the business. The business analyst works on understanding problems in depth: eliciting and analysing requirements, modelling processes and data, writing detailed stories and acceptance criteria and supporting the team and testers. In smaller teams one person may do both, but the PO decides what, while the BA clarifies how it should work.
23
Tell me about a time you mapped a process and discovered a major inefficiency.
Situation: vendor onboarding at my company took around 18 days and procurement blamed finance. Task: I was asked to map the AS-IS process. Action: I interviewed five roles, traced 25 recent vendor records through system timestamps and built a swimlane map. It showed that bank details were collected twice and verified by two teams separately. Result: we merged the steps into one checklist at intake, cut onboarding to 9 days and reduced rework emails by about half.
24
What is row-level security in Power BI and how do you set it up?
Row-level security restricts which rows a user can see in the same report. In Desktop you create roles under Manage Roles with a DAX filter, such as 'Region'[Manager Email] = USERPRINCIPALNAME() for dynamic RLS. You test with View as Role, publish, and then map users or groups to roles in the Service. Dynamic RLS with a mapping table scales better than creating one static role per region.
25
In UAT cycle 2, a feature that passed in cycle 1 is now broken after a defect fix. What does this tell you and what should change?
It is a regression: the fix for one defect broke existing functionality, which usually means changes were not impact-analysed and there is no regression suite. Log it as a new high-priority defect linked to the fix. Agree with the team that every UAT build comes with release notes listing the changes, and that QA runs an automated or core manual regression pack before handing the build to business testers. Also add the broken flow to the UAT regression checklist.
The income statement shows revenue, expenses and profit over a period. The balance sheet shows assets, liabilities and equity at a point in time. The cash flow statement shows cash from operating, investing and financing activities. They link together: net profit flows into retained earnings on the balance sheet and is the starting point of operating cash flow, and the closing cash balance from the cash flow statement equals cash on the balance sheet.
28
Tell me about a time UAT revealed a major issue that earlier testing missed.
Situation: a new claims system passed QA, but in UAT a claims officer tried a real scenario with two policies on one claim. Task: as BA I had to assess and resolve it quickly. Action: I confirmed the requirement never covered multi-policy claims, quantified that 8 percent of claims were affected, and agreed a manual workaround while the change was built. Result: we went live on time, delivered the fix in the next release, and I added real case samples to future test design.
A balanced scorecard is a strategic performance framework that tracks objectives and KPIs across four perspectives: financial (revenue growth, margin), customer (NPS, retention), internal processes (cycle time, defect rate) and learning and growth (training hours, employee engagement). The idea is that financial results are lagging, so leaders also need leading measures of what drives future performance. A strategy map links the objectives with cause-and-effect arrows from people to processes to customers to financial outcomes.

Write a defect report for an invoice that calculates GST incorrectly.
Title: Invoice applies 12 percent GST instead of 18 percent for service items. Environment: UAT, build 2.4.1. Steps: create an order with service item SRV-101 at 1,000 rupees for a customer in Maharashtra and generate the invoice. Expected: CGST 90 and SGST 90, total 1,180. Actual: CGST 60 and SGST 60, total 1,120. Severity: high, as it affects tax compliance. Attachments: invoice PDF and screenshot. Linked requirement: FR-TAX-07.
31
What does expectation management mean for a business analyst?
It means making sure stakeholders know realistically what will be delivered, when, and with what limits, before they form their own assumptions. A BA confirms scope in writing, states assumptions and dependencies, shares estimates with ranges, and flags risks early. When something changes, they update stakeholders immediately with options. Most stakeholder conflict comes from surprises, not from bad news itself.
32
What is AS-IS and TO-BE process modelling, and where does BPMN fit in?
AS-IS modelling documents how a process works today, including pain points, delays and handoffs. TO-BE modelling shows the improved future process after changes or a new system. Comparing the two reveals the gaps and requirements. BPMN, Business Process Model and Notation, is the standard notation, using events, tasks, gateways for decisions and swimlanes for roles, so both business and IT read the diagrams the same way.
33
Write an Excel formula to count the number of unique customers in a column.
// Excel 365
=COUNTA(UNIQUE(A2:A500))
// unique customers in the North region only
=COUNTA(UNIQUE(FILTER(A2:A500, B2:B500="North")))
// older versions (no blanks in range)
=SUMPRODUCT(1/COUNTIF(A2:A500, A2:A500))
34
What are DAU, WAU and MAU, and what is the stickiness ratio?
DAU, WAU and MAU count unique users active in a day, week and month, where 'active' must be clearly defined, such as completing a core action. The stickiness ratio is DAU divided by MAU and shows how often monthly users return. A ratio of 0.5 means the average monthly user is active about 15 days a month. Daily-use products like messaging aim high, while a travel app naturally has low stickiness.
The Ansoff matrix maps four growth strategies by product and market. Market penetration sells existing products to existing markets, the lowest risk. Product development offers new products to existing customers. Market development takes existing products to new markets, such as new cities. Diversification launches new products in new markets, the highest risk. In a growth case it structures the options before you evaluate each one's size, cost and fit.
Usually the values only look the same. Common causes are trailing or leading spaces, numbers stored as text in one sheet and as numbers in the other, non-breaking spaces from web exports, or different spellings. Check with =LEN() and =ISNUMBER(), clean with TRIM, CLEAN or VALUE, and confirm the lookup range covers all rows and uses exact match. Wrap the final formula in IFNA to label true misses.
39
Revenue grew 20 percent this quarter but the number of active customers stayed flat. How do you interpret it?
Growth came from more value per customer, not more customers. Break revenue into customers times orders per customer times average order value to see which moved. It could be price increases, larger baskets, a shift to premium products or a few large accounts. Then check risks: is new customer acquisition stalling, is churn being masked, and is growth concentrated in a small segment that could leave?
40
A new TO-BE process went live three months ago. How do you prove that the improvement actually worked?
Compare against the baseline you measured before the change, using the same definitions: cycle time, first-time-right rate, cost per case, backlog and customer complaints. Pull data from system timestamps rather than surveys. Check that the gain is not explained by lower volumes or seasonality, ideally by comparing similar periods. Also check for side effects, such as faster processing but more rework downstream. Present the before-and-after with the business owner, and note where adoption is still incomplete.
