Fragen im Vorstellungsgespräch für Beschäftigung als Software Engineer Java Developer bei TechTree IT Systems

The interview process was simple and difficulty level was also average. First round was just an online test with some mcq question and 2 easy coding question. Then, the second and third round was technical interview in which they asked questions mostly related to Java and from my existing company projects. After clearing all rounds, I went to the HR discussion in which they agreed to offer me what I was expecting and asked me to send the last three months pay slip. But, after few days they told me that we cannot consider you as we do not have budget to offer you that package. I would say, it was totally waste of time, it took around two weeks and even after clearing all rounds finally they said they don't have budget.
