Senior Software Engineer Interview

Senior Software Engineer
Wrocław (Poland)

I applied online and the process took 7 weeks - interviewed at Nokia Solutions and Networks in September 2012.

Interview Details – No HR interview with typical questions, only an interview with four developers. This position was mainly about software design in C++, but there were no questions on software design. The interviewers seemed to be in hurry. Many questions unrelated to the position. They expect dictionary definitions as the answers.

Time and money wasting for experienced looking for a better paid job. It takes them extremely long time to make and inform their final decision, you have to ask them for that from time to time. Rude interviewers. Unprofessional and _no_reimbursement_.

Interview Questions

  • Testing techniques (black-box, white-box, regression, unit testing - they expect the answer from the book, not from your experience and the real-world programming), testing strategies (not assertions, mocking and so on... but answer as it is defined in one of the books they have probably read before).   Answer Question
  • Implement an algorithm to find balance point of the array. Proposed one, with average complexity of O(N-1) but it seems they were looking for another one solution (which I have found on Stackoverflow later).   Answer Question
  • What's wrong with this code (they were looking for "exact answer from the book" not what you can observe in the particular code example).   Answer Question
  • What is polymorphism (in-deep question (vtables, vptrs implementation details) with example on whiteboard, marking as virtual in base and not-marking as virtual in derived - what would happen)?   Answer Question
  • What comes along with copy-constructor? (Silly question, correct answer is assignment operator). Plus standard questions on memory leaks, mutex and semaphore, difference between stack and heap, overloading of operator new, etc. No questions on "advanced" C++ features like templates.   Answer Question
