Cognizant interview questions

Their server very down on that day, in technical round you will be interviewed by 2 persons ( working professional and hr team member) . For my friends they asked oops concepts,sql, rest api ,etc....

1 Technical 1 Technical Manager 1 HR I am sure many people will agree with me that worst HR communication happen here. No matter if you clear the interview or whatever they won't reply as if they have sweared on their life. Pathetic experience, i cleared their interviews every weekend for 4 weeks and every time it was ghosting. They just hire for the HR work to be highlighted.
