IDEA Cellular Human Resources interview questions

The initial stage of interview was VC and then invited for F2F in their Cochin office. They confirmed that they will reimburse the ticket expense and provide hotel accommodation. Interview was scheduled for 09:30 am and the HR met me at 11:00 am and asked me to meet the CEO. As per the schedule the meeting with CEO was at 09:30 am and finally got a chance to meet him at 03:30 pm. If they make a candidate wait for 6 hours , you can imagine how they can perform. They collected my ticket and invoice and confirmed they will send the reimbursement to my bank account. Even after 2 follow up they didn't even paid the money or don't even bother to reply. I really didn't expect it from a company like Birla. If they invite for an interview outside your city makesure you don't get cheated like me. Let them give the ticket rather than reimbursement.
