int Q : What if 1 M test cases are given to automate in a day

[Ankur]

These questions may be asked to gauge how a candidate behaves under pressure/crunch situation. Before going to start answering such questions, rather start questioning the interviewer himself/herself.

Here is the sample conversation:

You:

1. What type of product is that which requires a 'million' test cases?
   
2. Have you/your team manually tested all these test cases at least once?
   
3. How much time you/your team took to do the testing in pt 2?
   
4. Do all the test cases comes under the heading of "regression testing". I assume the 'million' test cases comprise of white box/black box.
   
5. What is your definition of 'automation'?
   

These are some few questions that come from the top of my head,may be others can add more to it... A sane interviewer should then go on explaining his points...
In case he says

Interviewer:
I don't care, I need an answer.

You:
I need 1 million resources.

Interviewer:
You are joking.

You:
You started it first.
