Openet Graduate Software Developer interview questions

Had an original conversation with a manager, talked about my background and past school work. Was later scheduled for an interview with a group of different developers. The questions were mainly basic Java and Object Oriented based questions, nothing hard or difficult. About a week or two after I was invited to the office and got to meet with several managers and developers. I got my offer letter there and got assigned a due date. I spoke with one of the managers about the position and salary, it was stated that he would look into making the changes and possibly getting a revised version. Over the next week the manager did not respond to any of my emails and questions that I had emailed. On the day of the due date I get an angry call from a different person in the company whom had been very upset because I had not accepted the offer. Very unprofessional.

Then after clearing this there was face to face interview in their head office where again process was divided into 4 parts which includes group poject presentation HR and technical
