Nuix interview questions

HR emailed for first interview and did not call at the decided time for the interview. After few hours, I sent an email and HR replied that they got busy, apologised and rescheduled the interview. At the next interview time, HR called in and asked few general questions to judge about my experience and know how regarding Nuix and its products. It went well but they asked about my salary expectation. I said that I am looking for a competitive salary but I won’t like to tell a figure at this time. They then asked about my current salary and insisted that I give them an idea. I told them about it roughly and that interview was finished. I asked them about next step if selected and they said that there will be 2-3 rounds of technical interviews. Interview was all well but I got email from HR after 5 days that they are not going ahead with my application. That’s all fine as it is their decision but I know my profile and my skills matched the job description well.. I have never been rejected like this at step one. I can clearly tell that they judged on the base of my current salary that they won’t be able to offer me a higher salary if I go ahead so they rejected me at first step. Good luck to them.
