During the initial stage of the interview process, I was tasked with developing a PowerBI dashboard. However, I was ultimately rejected with vague answers. This left me with the impression that the company was more interested in obtaining free dashboards rather than conducting a genuine interview; the interviewer was very unprofessional. My advice to anyone going through a similar interview process is to refrain from completing any tasks until you have successfully passed all the other stages. Otherwise, you may find yourself spending unnecessary time on a task that ultimately doesn't contribute to your progress in the interview process.
