Oracle Software Engineer(Internship) interview questions

He tenido 4 entrevistas diferentes, cada una con un equipo diferente. 2 fueron para puestos de Back-end en la base de datos de Oracle, otra de un nuevo proyecto que tenían y otra para front-end que no me interesó

Initial interview with recruiter who asked some basic techinical questions about OOP and functional programming. Was then sent a simple coding challenge that takes a text file stored on disk and returns some statistics about the text, such as word count and most common letter etc. Finally had another technical interview with a Lead developer, where I had to talk through my code and describe why I chose the methods I did. We also talked a bit about my previous projects mentioned in my CV.
