PwC Senior Software Developer interview questions

Got reached out to a recruiter through LinkedIn. Recruiter was super nice & spoke about a lot of things I’m interested in learning when it comes to software development. Went to the next round & spoke with the director and Senior manager. The entire time I was interviewing, the director just kept trying to one up for no reason & just trying to undermine my skills that I have learned over the past years & just try to iterate that he was “better” than me. Before the interview even ended, I sent my recruiter an email claiming I wouldn’t move forward due to how disrespectful the interviewer was

Process was very easy. I was supposed to have 3 rounds. 1st round technical basic questions were asked. 2nd round interviewer dint attend call, it was rescheduled twice and at third time interviewer agin dint join. But HR said that we gone through resume and you hiring manager is ok to proceed with you. In 3rd round, HR asked for expected salary, they said it is out of budget. Whatever you are holding currently is our budget. :/ they dint know this earlier???????
