HRs are very irresponsible and happy to waste candidates' time. I applied for the position few weeks, received a confirmation from HR for moving forward. Scheduled and confirmed 1st call with her, I adjusted my working day to attend the call. I received 1 hr prior to call saying her calendar is overlapping. I understood that it happens sometimes, I rescheduled for next week, waited for 30 mins, she never called. I sent her an email if is there any update, she said she was unable to call on my number, which is entirely unbelievable that I would not been reachable, if so she should have sent me an email right away if she could not give me a call. Please be professional enough to inform a candidate that you are no longer interested, stop scheduling fake calls.
