Overall tests were easy but due to very less number of seats (only 6 General in my region i.e. Kolkata) the competition was severe.
For JCA post, there was no interview but two rounds of online tests.
The first round was aptitude test consisting of numerical aptitude, logical reasoning, English & technical section (basic CS/IT related questions). Question level was very easy, each question carried 1 marks, total 100 questions were there.
Those who qualified in the first stage were called for Skill test (2nd round). This round consisted of around 10 questions. The questions were from C programming, Computer network, MS Office etc. The questions were not short questions rather implementation/practical kind of questions. Difficulty level was moderate.
