One 20 - 30 minute long phone screening interview followed by a one hour long in person interview with a technical component. The in-person interview was casual. It had two technical components. First, high-level questions regarding JS and React, in which I was asked to describe under the hood behaviours. Second, a whiteboard style algorithm question in which I was asked how I could determine if two shapes were overlapping.

Phone interview first then in person interview. It was an hour in person interview. Overall positive interview. But not a very practical one. Some questions are like typical computer sicence quiz questions. My feedback is that the interviewers can be more prepare for the interview. They have only asked very general questions. For example they asked what is a reducer and what is state vs props. I gave that what I could think of at the time of interview. They rejected me because they think my react/redux skills are too basic. But My suggestion is that If they wanted more then you could try to be more specific and have prepared for better questions. Or they can even provide a mock product and doing a bit of pair programming. By asking book questions dont always get the best out of your candidate.
