Oracle Senior Software Engineer interview questions

After 3 technical and 3 manager/ director rounds I got offer after 1 and half year. Interview questions were technical only.There were 2 telephonic technical interviews and then one face to face. in face to face interview questions were scenario based but much theoretical.

one phone interview + one online paper test + two onsite interview 1. the phone interview, about 20 mins, some basic information; describe the job you do at your current company; some java basic knowledge, like collection, hashmap & hashtable etc. 2. the paper test, it took 2.5 hour, so so so long! Describe a scenario, you want to design the database, the classes, and some questions about web development, linux, algorithm etc. A lot of questions. 3. two face-to-face interview: some basic computer science questions.
