In Time Tec Manual Testing interview questions

The worst interview experience i had . They called for Manual Testing position and asking questions related to Performance testing profile. And in every company there will be having their own company standards and procedures and i answered correctly as per our company's testing process we follow and they are telling it as wrong eventhough i gave correct answesrs. Please think for which position you are hiring before calling a person for interview and asking unrelated questions and wasting time of a person. Also i had a gap due to personal reasons and they knew it before and they called me for interview. In 2nd round they are telling i have gap and all. It doesn't make any sense.
