Software AG Senior Software Engineer interview questions

I interviewed for the position of Senior Software Developer - Natural Application Integration OS (Adabas & Natural). From the outset, the hiring manager expressed surprise that my CV had been shortlisted, as it did not reflect experience with C/C++. I clarified that the job description did not specifically require C/C++ but focused on middleware services to integrate with the platform, which seemed to address his concerns. He proceeded to ask several technical questions and agreed to arrange a second technical interview with a senior developer, who was on vacation at the time. The interview was initially scheduled for the day following the developer’s return, but I requested a reschedule, which was accommodated for the next working day. However, two hours before the rescheduled interview, I received a rejection email stating that another candidate had been selected and offered the position. This was both disappointing and felt unfair, as my skills were not fully evaluated during the process.
