The two engineers who interviewed me were not very friendly. I could tell they didn't want to be there. They were more interested in laughing when I tried to answer to the best of my ability but couldn't quite explain it correctly. This made the experience pretty terrible, as when they first laughed because I couldn't answer something, I just felt defeated and didn't want to continue the interview. Very unprofessional. I could sit there and ask them about a language they don't know and laugh too.

They asked me about Node.js experience, then what sort of testing I used. They also asked basic React questions:

• What is a callback function?
• What is a promise?
• What are the three steps of a promise?
• What are hooks and how do you use them?

What is the output of the following lines of code?

javascript console.log('Step1'); setTimeout(() => console.log('Step2'), 0); Promise.resolve('Step3').then((res) => console.log(res)); console.log('Step4');

You are given a string S consisting of N letters 'a' and/or 'b'. In one move, you can swap one letter for the other ('a' for 'b' or 'b' for 'a'). Write a function solution that, given such a string S, returns the minimum number of moves required to obtain a string containing no instances of three identical consecutive letters.
