Delphi Technologies Software Engineer(Internship) interview questions

Got referred internally, and HR contacted me for the initial screening process. Later I had phone interview with one of the hiring manager. He explained the roles and responsibilities, expectations and the general working environment. For third round I was called for an onsite face-to-face interview, there was a panel of three people and I was asked to create a presentation for a problem statement. The discussion went on for sometime, the whole process took two hours. And I haven't heard back, been more than two months now. There was no response from HR.
