Tesla interview questions

2 rounds back to back for 45mins . Both started with an intro , resume overview , system design and then a technical round. For real time system roles system design questions revolved heavily around what type of real time system would you choose in a particular situation (hard or soft real time) . How would you use interprocess communication

Smooth, friendly, conversational. The interviewer was very open about the position and described the role. The interview was very conversational and approachable. He was very understanding when I made mistakes and excuraged taking through your thought process
