GE HealthCare Sr. Software Engineer interview questions

Interview went smoothly but the HR that was handling the aftermath was very bad and poor at her ethics. Would not recommend this to anyone. Gave and cleared all the rounds of interview for 2 different teams. HR gave a confirmation that I was selected for the role and offer letter would be rolled out soon. The HR at GE Healthcare mistreats the candidates, she didn't bother to call, pick the call or respond to any of my messages/emails after her confirming the role. I had canceled/rescheduled multiple of my commitments just for the interviews and on a hope that I would hear back from the HR. But at GE, they do not seem to value or respect people's time. Lucky for me that I didn't put my papers in the current organisation else I would've been humiliated by now.

3 Rounds of Technical rounds. Everything went very well. In the 3rd round end, Manager asked me the salary expectation. I told the same thing which I have told when HR has called me 1st. Then suddenly everything has changed. He told me that salary is not a problem, but we need someone who can join immediately within a week. I told that I have already told HR about my notice period, then why it is coming now? I got to know the intentions to make the candidate get agree with less salary. I called the HR after 3 days and she told me that I am not selected. So it is very clear that, they want people with less salary, but want the candidate to know everything, typically everything. Questions were asked from, C#, OOPS, .Net Framework, CLR, GC, SOLID Principle, Design patterns, SQL Server, WPF, WCF. DONT give interview to this company if you dont want to waste your valuable time. HR will never respond. Very bad HR Team I can say.
