I have given multiple interview for application packaging however I have not cleared or received offer letter.

Everytime, something happens. So, i have been trying to upskill myself after every interview and work hard for the next interview. My interviews are going good but not 100% perfect. They are asking scenario based questions which I have answered few, and for few gave the approaches. For a 4 years experienced application packager, is it normal to know everything? I have been trying to switch, I have learnt SCCM and intune as well, as they were asking these things for application packaging. However, in my organisation, there is a separate team for deployment. Even MNCs are not hiring and expecting everything from a candidate. They should know, admin studio, SCCM, psadt, script, intune, windows Installer, and deep knowledge in these things. I don't know if I can switch or not, cause in every interview they ask something different. For example, today I was asked, if a msi is corrupted on client device and it is not uninstalling. Now, vendor has provided the msi with same product code. Now I need to install the msi without uninstalling the corrupted msi from client device. Since both have same product code and we cannot even uninstall and we cannot change vendor msi not we can use the transform. Later, after the interview, when I asked him about this question, he told, he was trying to get a approach as in his organisation, these type of scenarios , he is facing. So, how I can know every possible scenario. I have given him the answers for powershell script, intune, SCCM, drivers etc, but, I am stuck at this question. The interview was for TCS. I don't know, why everyone don't want to provide an opportunity atleast. I can learn, I can troubleshoot, I can grow, but atleast see the potential instead of rejecting for just one or two questions.
