Etex Data Engineer interview questions

Had to go through first HR screening then was invited for a second and final interview. It was really intensive since I had to meet a lot of people for like 3 hours straight. After that, the HR called to say they want to make an offer but they need one reference to call. I gave them that and from what I understood it went fine. Then they disappeared and came back with another request. They wanted to see my payslip. I first said no, then they insisted, otherwise they wouldn't extend an offer. I agreed and sent it to them. After waiting for few days of silence, I called. Another HR member picked up to say they won't offer me the job because there's no budget. Of course, it's a BS excuse. Lesson learned, NEVER show you payslip. It's irrelevant. If they threaten you to not send an offer, then that shows who they are.
