I completed this interview with the whole familiy earlier this year. We were successful and I think there was still a large margin. I expect if you do not know something they would ask easier questions to find some solid ground in your understanding of the Swiss political system.
We spent the largest part of the time talking about the topics of the "votations". We each explained one of our choice, and then he asked us about some others that he picked. The interviewer also asked if we knew the outcome of the vote for the examples, but this was already framed as a "bonus question".
About knowing the names of the politicians, I'm not sure how important it is. My wife did not know the mayor of our commune, and the question had first been put only to her. Anyway, the interviewer put it to the whole family next and I knew the name of the mayor (plus his party and what he studied - I think I overdid it a bit). It may depend on the interviewer if they want you to know all the members of the Federal Council and their areas of responsibility.
The few hard facts are embedded in a lot of chit chat, for example if you noticed any topics that are of interest in Geneva (e.g. shortage of housing, traffic problems...) And of course the question why you want to be Swiss.
Let me know if you are interested in more details.
