HR contacted me over LinkedIn. After a couple of phone interactions, HR asked me to be available for half a day with only one day's prior notice. They were not flexible to postpone. I was present at the scheduled time.

They made me wait for 45 minutes, and finally, the interviewer arrived. The interview went for around 1 hour, and they asked me to wait further. They made me wait for another 45 minutes. When I contacted HR, he was clueless and asked me to leave for the day. HR never got back, though he said he would.

If there is such unprofessional treatment for an interview candidate, I wonder how they treat their employees.
