There is no clarity provided by recruiter for the each round expectation. The recruiter says, it's a secret maintained by senior managment. You can imagine how professional the org is, even during the process they won't reply back, sharing interview feedback is way beyond expectations. Unstructured process gives clear insight about the org,

These guys don't know how to conduct a proper interview. One interviewer showed up a few minutes late, then wasted all his time inquiring about my background, and forgot to ask the technical question he was supposed to. Two other interviewers spent their time fishing for very particular answers without being specific about what they wanted, even after asking for clarification. Due to this I gave them details on possible solutions depending on various conditions, which they seemed to ignore or not understand. They also made a couple of statements about performance, which I would disagree with because they only hold true under very specific conditions, not the general case... but maybe I misunderstood their intention, because as I've already stated, the interviewers weren't very good at explaining themselves. Oddly enough, the most worthwhile technical evaluation was a system design question given by the manager at the end, who wasn't supposed to be asking one at all.
