TRU Simulation + Training Aircraft Systems Simulation Engineer interview questions

After about 3 monthes of my applying this position in the website of the company, I was informed by the phone to get an opportunity to an interview with the Aircraft Systems Simulation Manager. The face-to-face interview was processed pretty well, and we have communicated a lot about my previous exprience ,the requirement of the position and the condition of the team. The manager is very kind and patient. After that i was required to take 2 tests using C++.Unfortunatly I am not familiar with the circuit diagram so I did not fulfil that well. The manager said that he would give me the answer in about one week. But I am still waiting for the result.
