Eaton Senior Software Developer interview questions

Before interview, the HR agreed for a 30% hike on my current CTC. I cleared 2 technical rounds and 1 Manager Round and then after the HR round, they told me they can’t even match my current CTC. The HRs wasted mine, 2 technical interviewers, and the manager’s time. They should get all necessary details like budget for the position before scheduling the interview.
