Trying to hover on a menu and click on a link in the sub-menu but no luck - selenium

Question

I am learning to hover over a menu and click on a link int he sub-menu.
The scenario is go to the URL "https://www.amazon.in", hover over "Hello Sign in" and then click on the link "Start here".
I can hover over "Hello Sign in" using moveToElement() and sub menu is opening, but couldn't click on the link "Start here".
Here is my code.
WebElement signUp = driver.findElement(By.id("nav-link-yourAccount"));
Actions action = new Actions(driver);
action.moveToElement(signUp).build().perform();
WebElement startHere =
wait.until(ExpectedConditions.visibilityOfElementLocated(By.linkText("Start here")));
startHere.click();

Answer 1

The link text includes a dot at the end, you missed it in your code, Try By.linkText("Start here.") or By.partialLinkText("Start here")

Answer 2

Please try the below modified code and it's working as expected. First you can find the new Customer Div and then directly access the start here link as below.
WebElement signUp = driver.findElement(By.id("nav-link-yourAccount"));
Actions action = new Actions(driver);
action.moveToElement(signUp).build().perform();
WebElement newCustomer=driver.findElement(By.id("nav-flyout-ya-newCust"));
newCustomer.findElement(By.xpath(".//a")).click();

To access the URL https://www.amazon.in then hover over Hello Sign in and then click on the link Start here. you have to induce WebDriverWait for the element with text as Hello Sign in to be visible, then Mouse Hover over it and then induce WebDriverWait for the element with text as Start here. to be clickable and you can use the following solution :
Code Block :
System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.amazon.in/");
WebElement signUp = new WebDriverWait(driver, 10).until(ExpectedConditions.visibilityOfElementLocated(By.id("nav-link-yourAccount")));
new Actions(driver).moveToElement(signUp).build().perform();
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.linkText("Start here."))).click();
