Hacker rank test after an initial screening with HR. I got passed the hacker rank test and video interview booked with 2 technical staff. The day came and no one turned up to the video conference. Contacted HR while waiting, said would look into it and then went silent too. No response after. A week or 2 later said HR person gets back to me with various excuses about the silence. I politely refuse and move on with my life.
