Travelex Java Developer interview questions

There were 2 technical rounds 1 managerial round And a small general hr round. They called again for a final hr round. The hr asked basic details, reason for job change, if comfortable working in shifts,etc. She told to wait 10mins after which the interview would start along with her and the manager. After waiting fr 15-20 mins she said u can leave. When I asked the reason, she said the hr would get back to you. It was a very unprofessional behaviour. All details like salary were already shared. Atleast a reason for not selecting must be told rather than wasting anyone's time. Advice-Please do not share your previous salary slips or other details with these people. They are very unprofessional. Do not reply to mails if asked reason for not selecting until then they talk too sweetly on the phone.
