They called and invited for the interview. At interview day interviewer called before 2 hours and she said she can not participate and than they postponed. This is acceptable you can have problem or health problem, we are all human.
After that at revised interview day they called 5 MINUTUES before the interview and they said they stopped hiring process! 5 MINUTES!! this is very disrespectfully! If there is another reason they should explain clearly, not 5 MINUTES before from the meeting!!!
