Working for Google may sound fun, but the interview process sure doesn’t.

After applying for a director of engineering role at the company, Pierre Gauthier — a computer engineer who started his own tech company 18 years ago — was asked some pretty intimidating questions in a phone interview.

After failing to give the Google recruiter the “right answers,” he decided to create a Gwan.com blog post to share the challenging questions, his response and candid thoughts with the public.

Though Gauthier managed to answer the first four questions correctly, it was all downhill from there. Gauthier soon found himself arguing his answers with the recruiter, and by the ninth question, he frustratedly asked, “What’s the point of this test?”

Basically, if Google ever calls you for an interview, here are ten questions you’ll want to know the answers to:

1. What is the opposite function of malloc() in C?

2. What Unix function lets a socket receive connections?

3. How many bytes are necessary to store a MAC address?

4. Sort the time taken by : CPU register read, disk seek time, context switch, system memory read.

5. What is a Linux inode?

6. What Linux function takes a path and returns an inode?

7. What is the name of the KILL signal?

8. Why Quicksort is the best sorting method?

9. There’s an array of 10,000 16-bit values, how do you count the bits most efficiently?

10. What is the type of the packets exchanged to establish a TCP connection?

Those sound like a joy, right?
