Intellect Design Arena Sr. Software Engineer interview questions

There are three rounds 2 technical and 1 machine test.

First online test at their office ,if you cleared it HR will tell to wait for technical interview.if you clear technical then they will call for managerial round . At last HR round will happen and in my case it was just salary discussion. Earlier they were ok for the salary I was expecting and scheduled my interview later on they denied. after two days HR told me that they have that project on hold for which they took my interview so in different project they have opportunity if you want you can come and again I have to go with same process from online assessment to HR. No proper plan and wasting the time of searchers.
