The ultimate guide to senior engineering interviews. Strategies developed by FAANG engineers on Python concurrency, multithreading, monitors, and event loops. Prep faster for top company questions.

Concurrency in Python is one of the most complex and advanced topics brought up during senior engineering interviews. Knowledge of concurrency and multithreading can put interviewees at a considerable advantage. This course lays the foundations of advanced concurrency and multithreading and explains concepts such as Monitors, Event Loops and Deferred Callbacks in depth. It also builds simple and complete solutions to popular concurrency problems that can be asked about in interviews like the Reader-Writer Problem and the Dining Philosopher Problem. While prior knowledge of concurrency is not required to follow through with this course, familiarity with the very basic Python would be helpful.

<p>The third and final option that can be chosen for the start method is the "forkserver". The official documentation states that with forkserver as the start method, a brand new single-threaded process, called server is started. Whenever, a new process needs to be created, the parent process connects to the server and requests that it forks a new process. Since the server process is single threaded, it can safely invoke <code class="mthd">os.fork()</code> to create a new process.</p>
