Questions posées lors d’un entretien d’embauche pour Java/Web Developer chez IBM

The first round of interview happened 30 mins from the scheduled time. Got a call from HR asking to drop off as the panel member is unavailable. After 30 mins, she called again asking if I could join and I did. Later she called saying that I cleared the first round .I was asked to submit the documents for further proceeding and to be available the whole day as the PDM round will happen. Hours later,I called the HR regarding an update and she informed that I’m kept on hold. I further inquired and she told “The panel got CONFUSED with the name”. After receiving all the documents and clearing the rounds, this is so unprofessional and unexpected from a well reputed company .
