1. Unprofessional as they only notify for an interview 24 hours prior. As if they expect everyone to be available at such a short notice. First sign of poor HR. 2. Poor interview process which is very simple case study. 3. As a result, many undeserving people are a part of the department. 4. Huge discrepancies in salaries. As big as 100-150%. No rational explanation but only demand-supply scenario. Another sign of unprofessional HR/Company.
