I had two interviews in a row for two different teams. The first one had all the official steps, telling about the company, myself, and what I'm responsible for, etc., while the second one had only technical questions. Each interview took 1.5 hours. Since it was my first interview, I'm not sure how hard it was, but for me, it wasn't easy.

1. How can you tell if a linked list has a loop in it or not?

2. Write a function that counts the amount of '1' bits in a given byte. Do it quicker later.

3. A complicated question about the reader/writer problem.

4. A few more questions.
