Siemens Senior Software Developer interview questions

1 Technical Written 2 Technical Rounds face to face 1 Managerial Round 1 HR Round Got selected , was waiting for the salary negotiation with HR. then they told project is on hold. Asked to take another interview round - 1 Technical Again 1 Managerial Again Was rejected as now the requirements were not meeting with the project.

According to the communication received it's a scheduled interview consisting 2 technical and one manager rounds followed by HR. Apparently their schedule is pathetic. Mine was supposed to happen at 2pm. These people don't seem to appreciate other's time. I met with people who came in at 10am and still waiting. Pathetic. I left after around two hours of waiting.
