1. [OA] Test Automation — Build a parallel testing framework for Rippling’s web application.
In order to ensure the quality of our rapidly evolving web application, Rippling needs an efficient mechanism to run UI tests concurrently across different browsers. This will speed up the release cycle while maintaining stability. Implement a function that facilitates running tests in parallel using Playwright/Selenium. - def run_tests_in_parallel(test_cases: List[str]) -> List[str]: Runs a list of provided test case scripts in parallel and returns their results. Example 1: Input: ["test_login", "test_dashboard", "test_settings"] Output: ['passed', 'failed', 'passed'] Explanation: The first and last test cases passed, while the second test case failed. Constraints: - 1 <= len(test_cases) <= 100 - Each test case is a valid string representing a test name.

2. [OA] Flaky Test Detector — design a system to identify and manage flaky tests in Rippling’s CI/CD pipeline.
Flaky tests can undermine the reliability of Rippling's software releases. Implement a class that collects results, tracks test history, and flags tests that show consistency in flakiness over time. - class FlakyTestDetector: - def __init__(self): Initializes the detector object. - def add_result(self, test_id: str, result: bool) -> None: Records the result of a test. - def is_flaky(self, test_id: str) -> bool: Determines if a specific test is flaky based on its results. Example 1: Input: detector = FlakyTestDetector(); detector.add_result('testA', True); detector.add_result('testA', False); detector.is_flaky('testA') Output: True Explanation: The test has failed at least once in its last few invocations, necessitating review. Constraints: - 1 <= test_id <= 10000 - Up to 1000 results can be recorded for each test.

3. [OA] LRU Cache — implement the caching layer Rippling uses for frequent API responses.
Rippling's services rely on efficient caching solutions to improve response times and reduce database load. You need to implement an LRU Cache that manages API responses effectively. - class LRUCache: - def __init__(self, capacity: int): Initializes the LRU Cache with a specified capacity. - def get(self, key: int) -> int: Returns the value for the specified key, or -1 if not found. - def put(self, key: int, value: int) -> None: Updates or inserts the value for the specified key. Example 1: Input: cache = LRUCache(2); cache.put(1, 1); cache.put(2, 2); cache.get(1) Output: 1 Explanation: Returns 1, as key 1 is present in the cache. Constraints: - 1 <= capacity <= 3000 - 0 <= key, value <= 10^4.
