How to prepare and behave

This is editorial guidance, not information from the employer.

• Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
• Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
• Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
• Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
• Be honest about gaps; say what you did to learn and how fast you can close them.
• Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
• When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
• Send a short thank-you message within a day, mentioning one thing you discussed.
• Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

Know your rights as a candidate and an employee:

• U.S. Equal Employment Opportunity Commission: prohibited employment practices
• U.S. Department of Labor: Wage and Hour Division
• CareerOneStop (U.S. Department of Labor): job search help, interview tips and resumes
• USA.gov: avoiding job scams

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 $1,233,200, which is 8.4 times the median household income ($146,427); a ratio above 5 usually means buying is out of reach without savings or a second income. 55.8% of households own their home, about the same as the state average (55.8% against 55.9%).

Work and pay

The San Jose-Sunnyvale-Santa Clara, CA metropolitan area has 1,134,970 jobs in the BLS wage survey, and the median pay across all occupations is $84,050 a year, 65% above the national median ($84,050 against $50,980).

The area is most specialised in computer and mathematical (3.9 times) and architecture and engineering (2.5 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($210,750) and legal ($195,190). In 2026M09 the unemployment rate of Santa Clara County was 4.2%. 67.6% of residents aged 16 and over are in the labour force. The city lies in Santa Clara County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 62.9% drive alone, 2.4% use public transit, 1.8% walk, 20.3% work from home. 15.3% of workers commute 45 minutes or more, 21% below the state average (15.3% against 19.4%).

People and education

47.3% of adults aged 25 and over hold a bachelor's degree or higher, 28% above the state share (47.3% against 37.1%). 42.0% of residents were born outside the United States, 56% above the state share (42.0% against 27.0%). The poverty rate is 8.1%, 32% below the state rate (8.1% against 12.0%).

Climate

The warmest month is Aug, averaging 68°F (19.8°C), and the coolest is Jan at 47°F (8.3°C). About 510 mm (20 inches) of precipitation falls in a year; Dec is the wettest month (114 mm) and Jul the driest (0 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.
