First, they came to my university for a presentation, and I gave them my resume. A week later, I was contacted by email to schedule a phone interview. The phone interview (about 20 minutes) consisted of questions like:

• How would you test a keyboard?
• What is the difference between threads and processes?
• Imagine you get home and find you don't have your keys. What would you do?

Then, I received an email about my phone interview, and the process for an interview at Microsoft began. Microsoft pays for flights, accommodation, taxis, and even your food.

I was interviewed by four different people. The interviews started with a few questions, and at the end, the interviewer presented a problem and asked me to solve it. Once I presented my solution, they asked me to code it on the board.

My advice is to keep talking and pay attention to the hints the interviewer gives you. If they notice you're doing something wrong, they'll probably make a comment that you can use to find the problem in your idea or code.

After coding, the interviewer will ask you to come up with test cases for your code. They are likely expecting many test cases, so think as much as possible about ways to break the code!

In the same week after my interview, I received an offer by email and accepted it.
