How to prepare and behave

This is editorial guidance, not information from the employer.

Know your rights as a candidate and an employee:

The city

The job is in Chantilly, VA. Below is what the official statistics say about living and working there.

How Chantilly compares. Among the 100 largest places in Virginia, Chantilly is #51 by population, #18 for homeownership (#1 = highest), #19 for household income (#1 = highest), #74 for rent (#1 = cheapest). Its county, Fairfax County, is #3 of 133 counties for average pay ($114,100).

The place in numbers

Chantilly has 24,036 residents (ACS 2020–2024), about 0.3% of the population of Virginia. It covers 12 square miles of land, which works out to roughly 2,003 people per square mile. The median age is 41.3, 6% older than the state median (41.3 against 39.0). It is a census-designated place: a community the Census Bureau counts as a unit, without a city government of its own, so services such as police, roads and zoning usually come from the county.

Housing

The median gross rent is $2,312 a month (rent plus utilities), 46% above the state median ($2,312 against $1,579). Over a year that is 17.7% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $663,600, which is 4.2 times the median household income ($157,124). 81.1% of households own their home, 20% above the state average (81.1% against 67.3%).

Work and pay

The Washington-Arlington-Alexandria, DC-VA-MD-WV metropolitan area has 3,136,190 jobs in the BLS wage survey, and the median pay across all occupations is $71,060 a year, 39% above the national median ($71,060 against $50,980). The biggest occupation groups are business and financial operations (369,190 jobs, median $105,260); management (319,760 jobs, median $165,010); office and administrative support (290,050 jobs, median $53,250). The area is most specialised in legal (2.6 times) and computer and mathematical (2.2 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are legal ($175,070) and management ($165,010). In 2026M09 the unemployment rate of Fairfax County was 3.4%. 69.8% of residents aged 16 and over are in the labour force. The city lies in Fairfax County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 59.3% drive alone, 1.6% use public transit, 1.5% walk, 24.2% work from home. 18.2% of workers commute 45 minutes or more, 4% above the state average (18.2% against 17.6%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.

People and education

59.7% of adults aged 25 and over hold a bachelor's degree or higher, 42% above the state share (59.7% against 42.2%). 42.9% of residents were born outside the United States, 227% above the state share (42.9% against 13.1%). The poverty rate is 5.8%, 41% below the state rate (5.8% against 9.9%).

Climate

The warmest month is Jul, averaging 78°F (25.6°C), and the coolest is Jan at 31°F (-0.4°C). About 1,117 mm (44 inches) of precipitation falls in a year; May is the wettest month (120 mm) and Jan the driest (65 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.

Nearby cities to compare

Closest cities in this guide: Franklin Farm (3 miles, rent 14% higher); Centreville (3 miles, similar rent); South Riding (4 miles, rent 26% higher); McNair (5 miles, similar rent). Rent differences are against Chantilly; use the Compare tab to put any two cities side by side.
