IBM Applications Developer interview questions

I had two interviews, one technical and one with an executive as well as a technical exam. The exam was a bit hard but the interviews were smooth and were not that difficult. You take the exam and when you pass, you do a technical interview and then the final interview is with the executive

there is 3 interviews The first one is technical asking about (OOP, algorithms, data structures, java, javascript,..etc ) the second one is behavioral asking about (leadership skills, and decision making.. etc) third one is with the team leader
