How many coding questions are in a 1 hour interview?

In a 1-hour coding interview, the number of coding questions typically ranges from 1 to 3, depending on their complexity and the company's interview process.

Breakdown:

• 1 Complex Problem: Many companies, especially those like Google and Facebook, may focus on one complex algorithmic problem that takes the majority of the interview to solve. The interviewer expects you to discuss your thought process, code the solution, optimize it, and handle edge cases during the session.

• 2 Medium Problems: Some companies might ask two medium-level problems. You’re expected to provide solutions in a reasonable time, with a focus on optimizing and explaining your code.

• 3 Short/Easier Problems: Occasionally, an interview could feature up to three smaller, more straightforward problems. These are typically designed to test your knowledge of data structures, basic algorithms, and your problem-solving speed.

Ultimately, the number depends on the complexity of the questions, the company’s style, and the interview format.
