Hiring that guy is a badge of honor because admitting otherwise would be to admit that the interview processes have nothing to do with the job, thus the real incompetence here is with the companies and people following that interviewing style.
Instead of correcting themselves, those interviewers chose to dive deeper into delusion.
So do all the worst - look at the extent to which hiring this Soham Parekh fellow has become a badge of honour instead of abject failure.
