First steps were a phone interview where they asked basic concepts of JS and about previous work experience. It was mostly a "get to know you" conversation with some easy tech questions at the end. Then was a coding task. I am not usually a fan of these considering the amount of time they take and because I don't feel they give good insight into the candidate's skill or knowledge. You are basically looking at someone's code in a silo with zero context other then the problem assigned. But, it looked simple enough so I completed it anyways. I completed the challenge and then was told they would not continue the interview process, but without any reason. They gave virtually no feedback from my submission which frustrated me because they expect you to spend up to 4 hours on the coding task, yet will not give the professional courtesy of constructive feedback afterward. I had no opportunity to explain my choices and have no idea what they liked or did not like from the assignment. Overall it was a very frustrating interview process for me. I spent a good amount of time on a very vague coding challenge and didn't receive the professional courtesy of constructive feedback for the time I put into my submission.
