The first interview was with an engineer from NetApp via Zoom. He started by asking about my experience and what I do in my current role, posing a couple of questions about it.

He then asked me a few technical questions. I answered one correctly, but for the other, he had to guide me to the answer. However, it was acceptable, as I advanced to the next phase.

In the second interview, a different engineer inquired in more detail about my current job and some technical aspects, such as how I2C works or questions about Linux kernel development.

After this, he asked me some questions about code he was sharing on his screen. With some assistance from him, I was able to answer all of his questions.

I received a rejection email a couple of days after this interview. When I asked for feedback on the reason for my rejection, the recruiter offered to schedule a call, which was a new experience for me.

During the call, he explained that I didn't have as much experience as they would have liked but encouraged me to apply for a new position soon.

What does this code do, and what is the pattern of its results?

c #define func(s) (s) & ((~s) + 1)

How does the I2C interface work?

What is the technique used to handle concurrency in the Linux kernel?

What is the result of this code?

c int x = 0x8000000;

x >>= 1; x: ?

In this code, what is constant? What line is allowed?

c int const *foo;

*foo = 0xdeadbeef; // allowed? foo = 0xdeadbeef; // allowed?

What about this code?

c const int *foo;

*foo = 0xdeadbeef; // allowed? foo = 0xdeadbeef; // allowed?
