“I was assigned to implement a new feature in our software that required a system call to an API which was new to me. I worked hard to understand the concept of API results, some of the questions I had solved myself and for some, I needed the help of the principal engineer of our team. I sent him a mail regarding those questions and asked if it is better to meet or if mail would be comfortable for him. He said it would be quicker to meet in person and was very helpful in answering those questions as well as giving some additional suggestions.”
