Oracle Data Center Technician interview questions

Seems like a good process but its not, completely unprofessional will string you along for almost a month and say they are on a hiring freezing. Spoke with an ex coworker says other team manager hire friends completely void the actual process of the interview. Don't bother when a recruiters contacts you they never follow up for an interview. Have to contact them all the time to get any updates. Worked in IT for 10 years not worth working for these large corps anymore.
