The interviewer will ask you more complex and ethical questions as the interview progresses. This is a natural progression and indicates that the interviewer is gaining confidence in your capabilities and is willing to challenge you more. Regardless of the difficulty of the question, continue to answer it in a similar manner. This will demonstrate your ability to be consistent throughout the interview.

When faced with a difficult question, you may or may not have all the information necessary to answer it. If you know part of the answer but not the complete answer, the best way to respond is to provide the information you already know and then describe how you would find the information you don't know. This is a better strategy than not answering the question or fabricating the information you are not aware of.

"A mutex, which stands for mutual exclusion, is a mechanism used to synchronize access to a resource. It only allows a single task, thread, or process to access the mutex. Ownership is associated with the mutex, and only the owner can release the lock.
A binary semaphore is a signaling mechanism that indicates the task is finished using the resource. A binary semaphore can be signaled by any thread, whereas a mutex can only release the thread it owns. This is the key difference between these."
