Interview Preparation Tips
Utter disregard for a candidate's time and work. The humiliating level of such degraded professionalism that they cannot decide before posting an interview that they don't want to hire.
But they have the audacity to expect 7 days and open-ended work schedule from the candidates.
DO NOT APPLY.
