I was contacted through LinkedIn and scheduled an interview. The interviewer was an hour late and later messaged me saying she was working from home and experiencing a blackout, so the interview was postponed to the following week. After the interview, I was given a test to complete within five days. I submitted it on time, but received no feedback or rejection. I even asked the HR person twice and she ghosted me. I'm disappointed it was very unprofessional to make me loose all that time and not even receive any feedback from the process. Overall, it was the worst experience I've ever had.
