Oracle Senior Software Engineer In Test interview questions

Basically I attended their open house. The first part is the HR gave us questionnaire that includes computer science concepts and other IT related stuff. Then after this, we are given coding test and another question for system design of employee database. After answering the coding test and system design, there will be two engineers that will interview you and will let you explain about your solution. After the interview, there will be a manager interview for behavioral aspect. Actually, after the manager interview, there was another interview from an engineer in Brno, Czech Republic. The interview is non-QA related. It was 100% coding problem. The Brno Engineer gave me two problems. The 1st one was the fizz buzz and the 2nd one is a simulation of coffee machine which the machine should have coins output on specified denomination. But after the Brno interview, I was informed that another team has an urgent need. So I will be joining a different team and with this, another interview. This time, from an engineer in Hyderabad. The engineer asked me about QA related questions and at the end, another programming question.
