  • If applicable, there might be inquiries on the identification of root causes of problems/bugs, the method of estimating tasks of various complexity.
  • Be ready to show your problem-solving skills, how you decompose the complex challenges.

Do you use live coding to test the knowledge?

  • Yes, in many cases we do, when sharp coding skills are vital for the position.
  • Make sure you are ready to code a simple challenge using relevant tech stack.
  • We don’t expect perfect and polished code, we are interested to see how you approach the problem and how much you can solve in a reasonable time.
