The interview was done by not very experienced technical interviewers. Questions coming from 2 out of 3 stages were not clear and not clarified later after my request. Some of the requirements also changed magically during an interview pointing me in the wrong direction. The interviewer's hints were also misleading and did not target the answer they wanted to get. Overall it was not an interview for a senior software engineer - more junior or mid position which was again misleading. I guess it might be hard to work with people when they can't communicate clearly.

All questions are under NDA.
