1) Since I have mentioned two projects developed using python in my resume, they started the questions towards python.

2) Asked about questions from my internship project. I have mentioned YAML Parser as one of the project, they asked how do you handle the corner cases and what are all the errors I have been aware of?
3) Asked some questions in data structure and asked me to write code

This round is manager round.
• If there’s an existing solution suggested by head or someone higher than me and there are other 2 solutions which is better according to me. But the problem here is, for the first case I would be accountable only for the implementation part not for the soln part. But for the other 3 solns I’ll accountable for both idea and implementation. Which will I choose?
(I answered this question in a way that I’m not scared of taking responsibilities)
• There is soft copy of some book, he gave print and then went to have coffee, But when he returns he found some page to be missing. What is the best way to find the missing page and assume that pages are in unsorted order?
• There is a 4 cross road and they were getting stuck due to the heavy traffic. How will you clear this situation? (Think it is in OS deadlock way, use bankers algo kind of thing to derive safe sequence).
• If I have allocated the memory of array with capacity of ten and returned the address of first value to me. How to detect the value 10 which is allocated?
(Since it’s contiguous memory I said on incrementing addresses after certain point, the order won’t be maintained BUT It’s Wrong )
