Spectrotel Software Engineer interview questions

This was more or less a general run through back in 2021, explaining what their architecture was, and relating it to my experience. They had moved to ASP.NET MVC at their developers requests from Webforms, though they felt it really wasn't necessary. I applied for another position this past month, and by this time they had shifted and were looking for someone with .NET Core, which is a significant change, and I wasn't interviewed. I suspect a change in tech management, and possibly issues with the limited amount of time MS supports versions of .NET Core,
