1) Hr video interview 2) coding task 1) regular Hr pre screening interview 2) reference to a coding platform with two tasks - backend and frontend. What is important to mention, that on HR interview we discussed my frontend skills and I told that I don't have any but would like to learn which was perfectly fine by the interviewer. Since the coding task consist of both, backend and frontend, I was told that backend part is more relevant for the role(just a reminder, role is not a full stack but backend engineer). Since I don't have any frontend knowledge I just skipped the task assuming that for backend position it would be enough to implement backend task well. I was wrong. The feedback was: "The Backend challenge looks good, but there is no implementation for frontend thus the task was not fulfilled." That looks strange, since the position is a backend one, and I warned about absence of my FE skills, but it was fine at that point... The main argument that I even didn't try to solve that challenge, however for that I would need to learn JS and React at least at the basic level in 1h, and even that won't help me to show some good results in FE task(for a backend position). As you probably have already got, that I kinda frustrated by rejection from BE position because of FE requirements, despite the fact I didn't set any wrong expectations about my FE skills and did BE part well. Looks a bit unprofessional and it was just a waste of time. My advice would be either make the position more clear. e.g. Full Stack Engineer or make it very clear about mandatory FE part, however in this case imho it would look wrong to reject candidates for BE position because of FE part. P.S. If other candidates told you that they don't have FE knowledge and then complete the FE task - they definitely lied(maybe to low the expectations) or cheated during task completion.
