I was contacted by the hr recruiter and had a 30 min phone interview regarding my CV and why I want to change jobs, the usual questions.I passed to the next step witch was the Assesment Center were I was needed to prepare a presentation.After the presentation witch was a 15 min one, I should have had an interview face2face with two of the hirreing managers present at the interview. I entered the interview last from my group and discovered that none of the managers were present ( business meetings) insted they send e diffrent one, with who I went ove my CV again.Afer this steps, the recruiter called me with the news that I passed and I will receve an ofer the next day.I didnt receve nothing for a couple of days, witch led me to send the recruiter an email. She responded that things in Oracle take a wile, but sje is working on getting the offer approved and get the contract in my hans.Weeks went pass like this, she excuseing herself that things are slow until I receved an email if I am interested top go for an interview for e diffrent position the next day. I accepted with led her to an reply at 9am telling me that I need to prepare another presentation.As you can imagine I stayd awake most of the night preparing for the interview. The interview was with 4 hireing managers. For the first two I needed to make my presentation, and them asking questions regarding it and the next 2 managers asking questions regarding my cv. All during this process I was receveing only bad feedback and listening how they thing that I could not fit the job.After a week I receved an email from their recruiter telling me that she is sorry but I didnt get the job. It was the worst experience I ever had interviewing for the job.Really unprofessional.I would never attend for another interview with or for Oracle.
