01
After many sprints, project documentation is out of date and new team members are confused.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 Keep living documents in a shared wiki with owners and last-reviewed dates, and archive outdated files clearly.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.
02
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.
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.
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.
Decide whether and how to enter a market by evaluating attractiveness, competition, capabilities and entry mode (build, buy, partner), then risks and next steps.
A self join joins a table to itself using two aliases, so you can compare rows within the same table. A classic business example is an employees table with a manager_id column: joining employees e to employees m on e.manager_id = m.employee_id lists each employee with their manager's name. Another example is finding customers who placed two orders on the same day by joining orders to orders on customer_id and date with different order IDs.
13
Write a SQL query to calculate the repeat purchase rate.
WITH per_customer AS (
SELECT customer_id, COUNT(DISTINCT order_id) AS orders
FROM orders
GROUP BY customer_id
)
SELECT
ROUND(100.0 * SUM(CASE WHEN orders >= 2 THEN 1 ELSE 0 END)
/ COUNT(*), 2) AS repeat_rate_pct
FROM per_customer;
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
Write SQL checks to validate a customer data migration between the legacy and new systems during UAT.
-- 1. Row counts should match
SELECT
(SELECT COUNT(*) FROM legacy.customers) AS legacy_rows,
(SELECT COUNT(*) FROM target.customers) AS target_rows;
-- 2. Records missing in the target
SELECT l.customer_id
FROM legacy.customers l
LEFT JOIN target.customers t ON t.customer_id = l.customer_id
WHERE t.customer_id IS NULL;
-- 3. Financial totals should reconcile
SELECT SUM(outstanding_balance) FROM legacy.customers;
SELECT SUM(outstanding_balance) FROM target.customers;
18
Tell me about a time your analysis changed a product decision.
Situation: the team planned to add more filters to the search page to fix low conversion. Task: I was asked to size the opportunity. Action: funnel analysis showed most drop-off happened after users opened a product page with no delivery date shown, not in search. I shared the data with session recordings. Result: the team prioritised showing delivery dates on the product page, conversion rose about 8 percent, and the filter work was deprioritised.
Working capital is current assets minus current liabilities, mainly receivables plus inventory minus payables. It is the money tied up in running daily operations. Too little means the company may struggle to pay suppliers and salaries; too much means cash is locked in slow inventory or unpaid customer invoices. Analysts track it because a growing business often needs more working capital, so fast growth can create cash shortages even when the business is profitable.
20
Split the epic 'Customers can track their order online' into user stories.
Possible stories: As a customer, I want to see my order status (placed, packed, shipped, delivered) so that I know its progress. As a customer, I want an SMS or email when the status changes so that I do not have to check. As a customer, I want the expected delivery date so that I can plan. As a customer, I want a courier tracking link once shipped. As support staff, I want to see the same timeline so that I can answer queries.
21
How do you influence stakeholders when you have no direct authority?
Build credibility with accurate work and by understanding each stakeholder's goals and pressures. Frame proposals in terms of their outcomes, such as cost saved or targets met, and back them with data. Involve them early so ideas feel shared, find allies who already support the change, and pilot small to show results. Be transparent about trade-offs. Influence comes from trust built over time, not one meeting.
22
Write a DAX measure that shows each category's percent share of total sales.
Incremental budgeting takes last year's budget and adjusts it by a percentage, which is quick but carries forward old inefficiencies. Zero-based budgeting starts every cost line from zero, and each activity must be justified by its value each cycle. ZBB uncovers waste and suits cost-reduction programmes, but takes much more effort and can create friction. Many companies apply ZBB to discretionary costs such as marketing and travel and use incremental methods elsewhere.
Use STAR: Situation, Task, Action, Result. Show that you listened, found the underlying goal, used data to align people and reached a documented decision.
26
What is user story mapping and how does it help plan releases?
User story mapping arranges stories in two dimensions. Across the top is the user journey as a sequence of activities, for example search, compare, buy and track. Below each activity, stories are stacked by priority. Drawing horizontal lines across the map creates release slices, where the first slice is a thin end-to-end MVP that covers every step at a basic level. It prevents a flat backlog where teams build one area deeply while the journey stays incomplete.
27
What checklist do you apply to a BPMN diagram before sharing it with stakeholders?
Every diagram has clear start and end events and a title with version and owner. Activities use verb-noun names such as Approve invoice. Each gateway is labelled with a question and its outgoing flows with answers. Splits and joins use matching gateway types. Message flows only connect separate pools. No dangling or crossing arrows where avoidable. The happy path reads left to right. Exceptions are handled, and complex rules are referenced to decision tables rather than drawn as gateways.
28
Write a SQL query to find the percentage of orders delivered late in each city.
-- late = delivered after the promised date
SELECT
city,
COUNT(*) AS total_orders,
SUM(CASE WHEN delivered_at > promised_at THEN 1 ELSE 0 END) AS late_orders,
ROUND(100.0 * SUM(CASE WHEN delivered_at > promised_at THEN 1 ELSE 0 END)
/ COUNT(*), 2) AS late_pct
FROM orders
WHERE status = 'DELIVERED'
GROUP BY city
ORDER BY late_pct DESC;
29
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.
30
Write an Excel formula that labels sales as High (100000 or more), Medium (50000 or more) or Low.
Costs: software 12 lakh in year 1 plus 3 lakh per year support, and 4 lakh for implementation and training. Benefits: 60,000 invoices a year at 10 minutes saved each is 10,000 hours; at 400 rupees per hour that is 40 lakh, plus around 5 lakh from fewer late-payment penalties. Year-1 net benefit is 45 - 16 = 29 lakh and payback is under six months. Then test sensitivity, for example if only half the time saving is realised.
32
Write an Excel formula for month-to-date sales up to today.
// Dates in Sales[Date], amounts in Sales[Amount]
=SUMIFS(Sales[Amount],
Sales[Date], ">=" & EOMONTH(TODAY(), -1) + 1,
Sales[Date], "<=" & TODAY())
// EOMONTH(TODAY(),-1)+1 gives the first day of the current month
33
Managers want to click a region on a summary report page and jump to a detail page for only that region. How do you build it in Power BI?
Use drill-through. Create a detail page, add the Region field to the page's drill-through filter well, and design visuals for orders, products and trends. Power BI adds a back button automatically. On the summary page, users right-click a region and choose Drill through. Keep all filters on so date selections carry over. For guided navigation, you can also add buttons with bookmarks, but drill-through is the cleanest way to pass the selected region.
34
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.
35
What does the LTV to CAC ratio tell you and what is a healthy value?
LTV to CAC compares the lifetime gross profit from a customer with the cost of acquiring them. A ratio around 3 to 1 is commonly treated as healthy. Below 1 means you lose money on every customer. Far above 5 may mean you are underinvesting in growth. Always compute LTV on gross margin, not revenue, and check it by channel, because blended averages hide loss-making channels.
36
Tell me about a time you led or mentored a team of analysts.
Situation: I led three junior analysts on a pricing review with a six-week deadline. Task: deliver quality work while developing them. Action: I split the work by workstream, set up short daily check-ins and a shared query library, reviewed their logic rather than rewriting it, and let each present their section to the client. Result: we delivered a week early, two juniors later handled client calls alone, and the review practice became standard in our team.
37
How do you write an effective executive summary for an analysis report?
Put it first and keep it to one page or five lines on a slide. Start with the answer or recommendation, then the two or three key findings that support it, each with a number, then the impact in rupees or percentage, and finally the decision or action needed and by when. Avoid methodology details, which go in the appendix. Test it by asking whether a busy leader could act after reading only this section.
38
What is the answer-first or pyramid principle approach to presenting analysis?
Start with the main conclusion or recommendation, then give the two or three supporting reasons, and only then the detailed data. Senior stakeholders have little time, so a summary like 'Churn rose because of payment failures; fixing retries can save 4 lakh a month' should come first. Detail goes in the appendix. It is the opposite of a chronological walk through every step of the analysis.
Clarify where the wait is measured: registration, consultation, diagnostics or billing. Split the problem into demand and capacity. On demand, check patient volume, peak-hour mix, walk-ins versus appointments and new departments. On capacity, check doctor availability, no-shows of staff, consultation time per patient and process bottlenecks such as manual billing. Identify the biggest stage and suggest fixes like slot-based appointments, triage and digital billing.
