01
What are the steps to publish and share a Power BI report with your team?
Save the .pbix and click Publish, choosing the team workspace. In the Service, set data source credentials and, for on-premises data, configure the gateway. Schedule refresh. Then share by giving workspace access to editors, or package it as an app for viewers, and apply row-level security roles if needed. Finally, check it on web and mobile and send the link with a short note on what each page answers.
Operating expenses here exclude depreciation. Gross profit is 50 - 30 = 20 crore. EBITDA is gross profit minus operating expenses: 20 - 12 = 8 crore. EBITDA margin is 8 / 50 = 16 percent. EBIT is EBITDA minus depreciation, 8 - 2 = 6 crore, which is a 12 percent operating margin. In an interview, state your assumption about whether operating expenses include depreciation, because that changes the answer.
04
Write a user story with acceptance criteria for password reset.
As a customer, I want to reset my password by email so that I can get back into my account.
Acceptance criteria:
• Reset link expires in 15 minutes
• Password rules are shown while typing
• A success message appears after reset
05
What is the difference between absolute, relative and mixed cell references in Excel?
A relative reference like A1 shifts when the formula is copied. An absolute reference like $A$1 stays fixed, useful for a tax rate or target cell. A mixed reference fixes only the column ($A1) or only the row (A$1), which is handy in multiplication grids or when copying a formula across months and products. Press F4 to cycle through the four options while editing a formula.
06
What is a power-interest grid and how do you use it?
A power-interest grid maps stakeholders by how much influence they have over the project and how interested or affected they are. High power and high interest: manage closely with regular involvement. High power, low interest: keep satisfied with concise updates. Low power, high interest: keep informed, for example end users. Low power, low interest: monitor. It helps a BA decide who to consult, how often and in what format.
SELECT c.customer_id, c.name
FROM customers c
LEFT JOIN orders o ON o.customer_id = c.customer_id
WHERE o.order_id IS NULL;
-- alternative
SELECT customer_id, name FROM customers c
WHERE NOT EXISTS (
SELECT 1 FROM orders o WHERE o.customer_id = c.customer_id
);
Scrum works in fixed sprints with defined roles such as product owner and scrum master, planned sprint goals and ceremonies like planning, review and retrospective. Kanban has no sprints: work flows continuously across a board, and work-in-progress limits on each column prevent overload. Kanban measures cycle time and throughput. Scrum suits product development with planned increments; Kanban suits support, operations and reporting requests that arrive unpredictably.
TAM, Total Addressable Market, is total demand for the product if every possible customer bought it. SAM, Serviceable Available Market, is the part you can reach with your model, geography and channels. SOM, Serviceable Obtainable Market, is the share you can realistically capture in the next few years given competition. For an online tutoring startup in India, TAM is all school students, SAM those online in target cities, SOM a small share of that.

Tell me about a time careful listening helped you uncover a hidden requirement.
Situation: during interviews for a new order system, a warehouse supervisor kept mentioning that Friday evenings were chaotic. Task: understand whether this mattered for the requirements. Action: instead of moving on, I asked what happened on Fridays and learned that bulk orders were split manually because of truck capacity limits. Result: we added an automatic order-splitting rule that nobody had listed, which saved the team about four hours a week and avoided a likely UAT failure.
AARRR breaks the customer lifecycle into five stages: Acquisition, how users find you; Activation, their first good experience; Retention, whether they come back; Referral, whether they recommend you; and Revenue, whether they pay. Each stage gets one or two metrics, such as sign-ups by channel, activation rate, Day-30 retention, invite rate and conversion to paid. It helps find which stage is the weakest bottleneck.
13
What are functional and non-functional requirements?
Functional requirements describe what the system does (login, reports); non-functional ones describe how well it does it (speed, security, availability, usability).
Both stack the results of two queries with the same number and type of columns. UNION removes duplicate rows, which needs a sort or hash step and is slower. UNION ALL keeps every row and is faster. Use UNION ALL when combining data such as online and store sales where duplicates are genuine or impossible, and UNION only when you specifically need a distinct list, such as unique customer IDs from two sources.
16
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.
17
A stakeholder asks for a detailed report by tomorrow, but it realistically needs a week. What do you do?
Understand the real need first: what decision is it for and what is the minimum that helps tomorrow? Offer a phased answer, such as a quick directional view with the top three numbers tomorrow, clearly labelled with caveats, and the full validated report in a week. Explain the trade-off between speed and accuracy. Confirm the agreed plan in writing so expectations are clear.
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.
21
What is horizontal and vertical analysis of financial statements?
Horizontal analysis compares line items across periods, showing growth, for example revenue up 18 percent year on year while employee costs grew 30 percent. Vertical analysis expresses each item as a percentage of a base within one period, such as each expense as a percentage of revenue, or each asset as a percentage of total assets. Together they show both trends and structure, and vertical analysis also makes companies of different size comparable.
22
Two analysts report different monthly active user numbers from the same database. How do you resolve it?
Put both queries side by side and compare definitions: which events count as active, time zone, calendar versus rolling month, test and internal accounts, deleted users, and DISTINCT on user ID versus device ID. Run both on a single day to find where they diverge. Agree on one definition with the metric owner, document it, and publish it as a shared view or metric so everyone queries the same logic.
23
What is the difference between gross margin and net margin?
Gross margin is revenue minus cost of goods sold, divided by revenue, and shows how profitable the product itself is. Net margin is net profit after all expenses, including salaries, rent, marketing, interest and tax, divided by revenue. A company can have a healthy 60 percent gross margin but a negative net margin if it overspends on marketing or overheads, which tells you where to look for fixes.
24
What is the difference between Power BI Desktop, Power BI Service and Power BI Mobile?
Power BI Desktop is the free Windows app where you connect to data, model it, write DAX and design reports. Power BI Service is the cloud portal where you publish reports, schedule refresh, build dashboards, set permissions and share with users. Power BI Mobile is the phone app for viewing reports on the go. A typical flow is build in Desktop, publish to a Service workspace, and consume on web or mobile.
25
Write Given-When-Then acceptance criteria for applying a discount coupon at checkout.
Given a cart of 1,200 rupees and a valid coupon SAVE10 with a minimum order of 1,000 rupees, when the user applies it, then 10 percent is deducted and the new total is shown. Given an expired coupon, when applied, then the message 'This coupon has expired' appears and the total is unchanged. Given a cart below the minimum, when applied, then the user is told how much more to add.
26
What are LOD expressions in Tableau and how do FIXED, INCLUDE and EXCLUDE differ?
Level of Detail expressions compute an aggregate at a granularity different from the view. FIXED computes at the stated dimensions regardless of the view, for example { FIXED [Customer ID] : MIN([Order Date]) } for first purchase date. INCLUDE adds a dimension to the view level, useful for average sales per customer by region. EXCLUDE removes a dimension, useful for comparing each month with the yearly total. FIXED ignores normal dimension filters unless they are context filters.
27
You added new rows to the source data, but your PivotTable does not show them even after refresh. Why?
The PivotTable source is probably a fixed range such as A1:F500, so rows added below 500 are outside it. The fix is to convert the data to an Excel Table with Ctrl+T and change the pivot's data source to the table name, so it expands automatically. Also check for blank header cells, filters on the pivot hiding new items, and whether the new rows are actually text values in a numeric column, which can change grouping.
Agile delivers value in small increments with feedback. Scrum organises work in sprints with planning, daily stand-ups, review and retrospective, led by a Scrum Master and Product Owner.
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.
Situation: two days before the go-live of a loyalty points system, UAT showed points were doubled for refunded orders. Task: give a clear recommendation at the go or no-go meeting. Action: I presented the defect, estimated financial exposure at about 6 lakh rupees a month and showed the fix needed three days including regression. Result: the sponsor agreed to a one-week delay. The release went live cleanly, and the sponsor later cited the decision as an example of good risk management.

What is COALESCE in SQL and how does it differ from ISNULL or IFNULL?
COALESCE returns the first non-NULL value from a list of expressions, for example COALESCE(mobile, landline, 'Not available'). It is ANSI standard and works in all major databases. ISNULL (SQL Server) and IFNULL (MySQL) accept only two arguments and are vendor-specific. Analysts commonly use COALESCE to show zero instead of NULL after a LEFT JOIN, such as COALESCE(SUM(o.amount), 0), so that customers without orders appear with zero revenue.
A data object (page shape with a folded corner) represents information that an activity needs or produces during one process instance, such as an invoice or an application form. It is linked with dotted associations. A data store (cylinder) represents information that persists beyond the process instance, such as the customer database or ERP. Showing them helps developers see which systems are read or updated at each step and helps spot missing integrations.
36
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.
37
What is the difference between revenue and profit?
A model classifying features as basic, performance or delight attributes based on how they affect customer satisfaction, helping decide what to build first.
39
Write a DAX measure for the product return rate that avoids divide-by-zero errors.
Return Rate % =
VAR ReturnedQty = SUM ( Returns[Quantity] )
VAR SoldQty = SUM ( Sales[Quantity] )
RETURN
DIVIDE ( ReturnedQty, SoldQty, 0 )
// DIVIDE returns the third argument (0) when SoldQty is zero or blank.
// Format the measure as a percentage in the model.
40
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.
