  3. Is DDT good for public health? (Discussion ensued and he gave me some info I was not aware of.)

  4. Okay, tell me about cryptocurrency and its implications.
  5. Tell me about demonetization and its implications.

Chairperson: Okay, your interview is over now. You can ask us anything.

Utility of mocks – I felt NextIAS was closer to the mark with respect to Choubey board. Vajirao was also somewhat similar in terms of current affairs asked. Overall, with this board prepare current affairs carefully as well as jump at any opportunity to show values and personality.

One on One with Republic IAS (Chennai – based institute) – found it very useful for tackling questions related to hobby especially choice based questions. Found it very good for building up confidence to tackle value based questions + to project one’s personality in GS based questions. Would recommend to anyone in Chennai and outside as well
