Smooch Software Developer interview questions

On site interview with 2 engineers and 1 hr staff. The interview lasted 1h 45minutes. The first half was behavior questions followed by a coding challenge at the end. The company is a startup so the office looks kinda messy, almost like a Starbucks. Interviewers were friendly, and a hr staff was there to help with the process. They will go through your c.v and ask about your personal projects. The coding challenge is exp based. And they will guide you through if you ever get stuck. You can also use external sources to help you. But do make sure that you have a good understanding of asynchronous programming.
