Canonical Software Developer interview questions

Applied online for the position mentioned above. The HR got back to me after about 3 weeks stating they had selected my resume (primarily for Qt skills). Had 2 rounds of telephonic interview, 1 hour each, in different timezones and both times the HR exec arranged the wrong time! 1st round was supposed to be by hiring manager, but it was coupled with a tech interview as well. Questions ranged mostly about my experience with Qt (my experience has mostly been in the multimedia embedded domain) and few on how signal/slots worked. Some elementary questions on hash tables and how they work. They also asked questions about how I would handle certain scenarios while working remotely. In the 1st interview, they said they'd let me know if I was selected/rejected for the next stage. For the 2nd round I was contacted within a few days. This round was with Unity API lead. The interviewer sent me a C++ header file, few mins before the interview, which was going to be discussed as part of the interview. This time the questions were pure C++ and OO desgin related. I'd never used exceptions (because of Qt usage) so got stumped there a little. But overall the interview went well. After that there was complete silence on their part for the next 3-4 weeks . Prodding the HR exec who had contacted me for the interview, finally revealed that they will not be processing my application to the next stage. I'm not sure what the reason for rejection was. Might be they did not find my C++ skills upto the mark or the fact that I was in India and they did not have any presence in India (so things like salary, tax etc might've been an issue). I'm saying this because this point, that how will I work remotely from India, came up during the 1st interview and the program manager did not really have an answer he told me that they'd have to 'figure something out'. Overall a good exp, apart from the lack of response from the HR.

The interviews consisted in 4 - 1 hour technical phone discussions with communication with HR in between. The interview process honestly was very disorganized with long periods of silence (3+ weeks) and an obvious lack of communication between each person / HR. The questions were not that technical, mostly to judge your level of maturity in development (some technical, also about QA, etc.), and overall interest / passion about software. Beware, not technical does not mean not "tricky", they probably expect a specific profile and an involved person that knows what he is talking about technically. They tried to probe this w/ some key questions. Besides that very good communication w/ tech managers (beside one which was so-so) and I enjoyed the talks.
