  • Q1. Suppose a customer gets a crash in our software and that crash dump comes to you for analysis - what would be your strategy to analyze the dump?

    I would start by identifying the root cause of the crash and then work on finding a solution to fix it.

Interview preparation tips for other job seekers - 2nd round was directly with director of engineering. It lasted from 10am - 4pm. Except bathroom breaks none of us stepped out of his cabin, not even for lunch.
He basically took all of my 'Janam kundli' from school life to adulthood - to guage the kind of person I was, asked about my technical interests, what interested me about the job, my experience so far, asked me hypothetical questions like -
-suppose a customer gets a crash in our software and that crash dump comes to you for analysis, what would be your strategy to analyze the bug?
-the callstack in the dump contains all other kind of info - like hardware/driver version, stacks of other threads etc -- how will you utilize this information to find root cause of crash?
-what kind of management style would you expect?
-how do you resolve conflicts? both in code and people.
-what kind of projects would inspire you to work here (he wanted my perspective on what I thought about job expectations)

I hadn't worked in such a large company before with so many moving parts so I couldn't really answer most of the above questions(the're based on experience) but it gave me much to think about. I tried to be as forthcoming as one can be during such situations, and I guess he liked that.

He also asked a bunch of technical questions - showed me a piece of code and said what would be its output, I said it won't compile. He repeated back twice 'are you sure' that made me doubt myself somewhat but I stuck by my logical conclusion. He didn't reveal whether I was right or wrong. Few questions to test understanding of inheritance in C++, virtual functions, recursion vs iteration.

I'm rating this interview experience as 3 because although I was selected, the opaque style of interviewing with virtually no feedback from him was quite frankly discouraging.
