Tech Mahindra PMO interview questions

The interview process was pathetic. They shortlisted and called over many people but didn't take interview. They were not even ready to disclose the position they were looking to hire for. They just sent all the candidates back saying your profile doesn't match the position's requirement. I don't know if they were even aware about the requirement and position. HR and the hiring department was clueless and roaming around. Made to wait all of us for 4 hours and said we are not able to take your interviews.
