Head Digital Works Frontend Developer interview questions

Unfortunately this was one of the worst interview experiences I've come across, not particularly because of the interviews themselves but more so because of the extremely callous and unprofessional behaviour all around. First round was an assignment round, beyond which I was invited to an online tech round. The interview went around 1 hour, with one interviewer disappearing midway. And at the end of the interview, the interviewer let me know that I've cleared this round. He also informed me of a managerial round which would be communicated to me later on. Surprisingly, my hiring contact had no clue about the results on the interview and asked me instead about the interview. And since then, they have completely ghosted me. Terrible miscommunication all around. Stay away.
