Is there anybody who got into IIM Lucknow after a bad interview experience?

My sister had a fairly poor interview experience and yet managed to get into IIM Lucknow. She was asked about the current issue of the world to which she mentioned the Syrian wars. He contradicted her saying it wasn’t a burning issue as it had been happening for more than 2 years. Flustered, she mentioned the US on the government's side. Further, the interviewer inquired her about her own opinion regarding the civil war. She confidently said that she couldn’t support any side due to the extremist quality of either of them. But the interviewer wasn’t satisfied and urged her to take a side and give a rather clear answer. 

The discussion continued for a few minutes after which he asked her about the Kashmir issue. 

After many diplomatic talks, he finally asked about her current role in the company and asked if she had any experience in E and P.

The interview was rather prolonged with a lot of contradictions and awkward situations. The interviewer kept cutting her off in the middle of answers. Toward the end, she was asked to solve a statistics problem which she managed to solve in 5 seconds. She was then asked to leave. She had little or no hopes of getting a call but as luck would have it she managed to get into IIM Lucknow.
