2. Explain an Excel spreadsheet and its components

An Excel spreadsheet consists of a grid system containing columns (labeled A to Z then AA to ZZ) and rows (labeled 1 to 1 million+). The intersection of a column and row is called a cell, which contains data.

Key components include:

  • Worksheets: A collection of cells across rows and columns. An Excel file can contain multiple worksheets.
  • Workbook: A Excel file containing one or more worksheets.
  • Cell: The basic unit of a worksheet storing data. Cells are referenced by addresses made up of their column letter and row number.
  • Formulas: Equations calculating values based on data in cells. Formulas start with an = sign.

Here is a visual overview:

3. What are some commonly used Excel formulas?

The most commonly used Excel formulas include:

Math formulas

  • SUM() – Sums a range of cells
  • AVERAGE() – Averages a range of cells
  • MAX() and MIN() – Finds maximum and minimum values
  • COUNT()– Counts number of cells with numbers

Logical formulas

  • IF() – Evaluates a true/false condition and returns one value if true, another if false
  • AND() / OR – Evaluates multiple true/false conditions

Lookup formulas

  • VLOOKUP() – Finds data in left-most table column and returns corresponding value from another column
  • INDEX(MATCH()) – More flexible alternative to VLOOKUP for complex data

Text formulas

  • LEFT() / RIGHT() – Extracts left/right parts of text string
  • TRIM() – Removes extra spaces before/after text

This covers some commonly used functions, but many more exist in Excel‘s library of over 400 functions.

4. How do you reference a cell in Excel?

Cells can be referenced using their column letter + row number, called the cell address.

For example:

  • Cell A1 refers to Column A, Row 1
  • Cell C11 refers to Column C, Row 11

This absolute referencing using cell addresses allows formulas to link to specific cell data.

Cells can also be referenced relative to their position. For example, if cell C1 contained the formula =A1+B1, it would add whatever values are currently present in the relative positions of cells A1 and B1. This relative referencing auto-updates and can expedite large analyses.

5. What are some commonly used Excel keyboard shortcuts?

Here some of the most popular Excel shortcuts:

  • Ctrl + C – Copy
  • Ctrl + V – Paste
  • Ctrl + Z – Undo
  • Ctrl + F – Find/Search
  • Ctrl + P – Print
  • Ctrl + S – Save
  • Ctrl + A – Select All
  • F2 – Edit selected cell

Learning keyboard shortcuts can greatly boost productivity since they reduce extensive use of the mouse to navigate options.

6. How can you format cells and text in Excel?

Excel provides a Home tab with basic formatting options for fonts, alignment, borders and styles.

Some examples include:

  • Changing font size, color, bold/italic
  • Applying number formats like percentage, currency, date
  • Changing text alignment: left, centered, right-aligned
  • Adding border lines around cells
  • Applying Styles for conditional formatting rules

The mini toolbar activated on cell selection also contains commonly used formatting options. Custom formatting rules can be defined as well.

7. What are Excel charts and what are they used for?

Excel charts are graphical representations of spreadsheet data used to visualize trends, relationships and patterns within large datasets. Their intuitive visual nature makes digesting and analyzing data much easier.

Excel offers 11 major chart types:

  • Column, bar, line
  • Pie
  • X-Y scatter
  • Stock
  • Surface
  • Doughnut
  • Bubble
  • Radar
  • Combo

Charts allow simple creation of clear, professional visualizations that can be inserted into reports and dashboards. Their datasets can also be dynamically tied to source data to auto-update when new data comes in.

Intermediate Excel Interview Questions

Let‘s move on to some Excel questions around more complex tools and analysis:

8. What are PivotTables? Explain their use cases.

PivotTables are interactive tables summarizing large amounts of data in Excel. They automatically group, count, total or average data stored in tabular format to uncover insights.

Key use cases include:

  • Summarizing large datasets – Condense huge datasets down using automatic grouping, summing and counting
  • Identifying trends & relationships – See across multiple data fields/metrics at once
  • Ad hoc querying – Interactively filter data on the fly to analyze from different angles
  • Comparing data – Add fields to Row/Column area to compare metrics across multiple dimensions
  • Data exploration – Uncover new perspectives by rearranging PivotTable fields

PivotTables save huge amounts of time in data analysis. Their flexibility and features make them invaluable for reporting.

9. How do you create a PivotChart linked to a PivotTable?

To create a PivotChart dynamically linked to changes in an existing PivotTable:

  1. Select PivotTable – Click any cell in the target PivotTable
  2. Go to Insert tab and click PivotChart button
  3. Choose desired PivotChart type in dialog box
  4. Modify chart details and filters further as needed
  5. Changing the underlying PivotTable data will automatically update the linked PivotChart graph

Linking PivotCharts to tables allow great dynamic reporting and dashboards surfacing insights as new data comes in.

10. What are some tips for clean data preparation before analysis in Excel?

Garbage in, garbage out. Here are tips for preparing raw data:

  • Value trimming – Trim unnecessary spaces before/after text values using TRIM()
  • Date formatting – Ensure dates consistently formatted for easy analysis
  • Error values – Scan for #N/A lookup errors indicating bad raw data
  • Blanks vs Zeroes – Confirm meaning; blank cells can undermine analysis
  • Naming ranges – Define printed range names referencing cell areas to use in formulas/tables for readability
  • Data validation – Configure validation rules restricting invalid data entry
  • Consistency – Ensure common values have consistent naming/formats across columns

While cleanup can be tedious, good data hygiene pays dividends in productive analysis.
