Human Resocia Software Developer interview questions

Online Screening, then Online interview. The communication is extremely disrespectful and rude throughout the process.They ask rudely why haven't you submitted the online exam even though I have already submitted. At the online interview stage, the manager is still incredible humiliating

Initially there will be a coding round. When I gave there was only one sum which I cleared although my one test case failed. If cleared interview will be scheduled after few days.
