Important Selenium Code / syntax below –  Quick Revision for Interview

// invoke the browser
driver.get("https://www.google.com/");

// Quit the browser
driver.quit();

// close the browser -
// if multiple window are open then
// it will close current window only
driver.close();

// Get the title of Page
driver.getTitle();

// Find Element in Selenium
By locator = By.xpath("");
WebElement element = driver.findElement(locator);

// Find all Element in Selenium with some locator
List<WebElement> list = driver.findElements(locator);
int totalelement = list.size();

// Send value in the Webelement (Generally used for sending value in input box)
element.sendKeys("some value");

// Get text value present in html
element.getText();

// Get attribute info - Example - getting value attribute of element
element.getAttribute("value");

// accept the alert
driver.switchTo().alert().accept();

// reject the alert
driver.switchTo().alert().dismiss();

// Get the windowhandle of current window where driver control is present
String currenthandle = driver.getWindowHandle();

// Get all window tabs - below is used for switching driver to different window
Set<String> listofhandles = driver.getWindowHandles();

// select dropdown options by visible text
Select select = new Select(element);
select.selectByVisibleText("Text");

// select dropdown options by index
int index = 0;
Select select = new Select(element);
select.selectByIndex(index);

Set<String> allwindows = driver.getWindowHandles();
Iterator<String> iteratoronset = allwindows.iterator();
String child_window = iteratoronset.next();

driver.switchTo().window(child_window);

// Explicit wait in selenium - return webelement
int timeout = 20;

WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(timeout));

return wait.until(ExpectedConditions.visibilityOf(element));

// Fluent wait in selenium - return webelement
int timeout = 20;
int pollingTime = 2;

Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
        .withTimeout(Duration.ofSeconds(timeout))
        .pollingEvery(Duration.ofSeconds(pollingTime))
        .ignoring(NoSuchElementException.class)
        .ignoring(StaleElementReferenceException.class);

return wait.until(ExpectedConditions.presenceOfElementLocated(locator));
