PwC Software Engineer Java Developer interview questions

It is a Skype call almost went for an hour. The interviewer is on time, but you'll not be able to see the interview panel members. There are almost 3 members who interviewed me.

Got a call from the recruitment team of PwC. The HR scheduled a telephonic round after few days. The pannel didn't turn up on that day and the HR is also not responding to my emails and calls. Certainly did not expect this kind of unprofessional behaviour from a brand as big as PwC.
