Peoplebox interview questions

Recruiter reached out to me on LinkedIn with JD to judge my interest. I got a call for the exploratory call. After I did not agree to disclose my last drawn salary, the interviewer ended the interview and decided we should not proceed. I received an automated mail next day that I have not moved on the next round. Fair enough. Few days later, I get a call from the same HR for the same role asking me pre-decided follow up questions saying, they did not send a rejection mail. They were also fine with my salary expectations this time. There was zero correlation in the conversation. After a few days I get a rejection mail again. Is this a joke??? Funnily they are a platform for talent management and recruitment. Please ensure you have senior people interviewing senior profiles.

It was detailed and very technical. Had 3 rounds each exploring different skill sets. There is more than what meets the eye. With Each round the difficulty increased Next round they take time to reach out
