Dear aspirants, anyone having any info about quota interview? Who can share his interview experience .looking forward

Quota interview will start in next month. A previous thread related to this is very old and at the same time lacks significant info. Anyone here who has appeared in this interview last year or know someone with same experience can be helpful. What type of questions are asked. If only current affairs, biodata and reasons to leave armed forces etc are asked? Or he is supposed to show knowledge of css subjects like EDS, ISL Pak affairs and geography etc? I am totally naive? Any help will be appreciated.
