In a C# interview, if you say "Async creates threads," your interview is almost done. The interviewer has already formed a weak perception about your understanding of the topic.
One of the most discussed topics during C# and .NET interviews is Async / Await / Threading / Task Parallel Library (TPL).
Many .NET developers struggle to answer questions on these topics, not because they have not worked with them. They use Async/Await every day and return Task objects throughout their code.
However, doing something mechanically and understanding or explaining the underlying concepts are two different things.
When you use state machines to explain Async/Await, it's a compelling message to the interviewer that you understand the topic well. Stressing the importance of futures in Tasks builds a different level of confidence.
Saying that Task is a higher-level abstraction over threads is only a partial answer. TPL has a much broader scope. It encompasses synchronous programming, asynchronous programming, and multithreading.
Debating Threads and Tasks without understanding concurrency and parallelism is an invitation to confusion.
Here are some questions asked by companies around Async/Await.
- Explain Async and Await and what happens underhood ? (LTree, Cog, Del)
- Difference between Async/Await and Thread? (Cog, Del, Ltree)
- Task vs Thread? (LTree , Cog)
- Does Async create threads? (Most Asked Questions section)
- What is ThreadPool Starvation? (Most Asked Questions section)
- What is the difference between ValueTask and Task? (Most Asked Questions section)
- Can the `ref` keyword be used in Async programming? (Most Asked Questions section)
- What is a Concurrency Issue, and how do you handle it? (Most Asked Questions section, Hex)
- Explain Thread Safety. (Cog, Hex)
- Explain Async Race Conditions. (Hex)
On Thursday, from 9 PM to 10 PM, at QuestPond.com , we will discuss this topic inside and out so that no question in a C# interview remains unanswered.
