I was contacted by a recruiter, who then set me up with a virtual interview. The interview was conducted in four parts:

• Behavioral
• Coding
• System design
• Code architecture

The first three interviews went okay. The interviewers were friendly. However, the final interview, which was the coding interview, was horrible. For some reason, the interviewer seemed irritated by me because I couldn’t understand the question, which wasn't clear enough. Anyway, I tried to understand, but she was rude. I was actually wondering if the color of my skin irritated her.

Design a chat application for the system design interview.

For the code architecture, design a vending machine.

For the coding interview, I didn't understand, so I don't remember.
