Just to clarify a few points:
I have come across a capacitor on the input which is to block DC; and also in the feedback loop which gives an Integrator function I believe however, in this circuit, there was a resistor in the feedback loop and another resistor and capacitor in series to ground from the inverting input?
Thinking about it now, could it form some sort of filter (High pass)?

Hi,
I was recently in a job interview and was asked to describe an OP-Amp
circuit.
The OP-Amp configuration consisted of negative feedback with a resistor
and capacitor connected in series to ground from the inverting input.
I haven't seen this configuration before and I was asked the purpose of
the capacitor?
No DC gain.
