Have been in Microsoft a couple years. Are there not any full stack roles?

Specifically curious with respect to building experience and performing well in interviews in the future. Prior to Microsoft I was able to do well in my interviews for behavioral / system design questions because I previously worked in a full stack role. However, I notice that most others in Microsoft are working on specific parts of the stack and I have not heard of any working in full stack roles. This is likely because most of Microsoft’s products are very mature. For those at Microsoft currently / been at Microsoft in the past, was this your experience and did it hold you back? I miss getting to look at the whole picture and as the years have passed I now realize I have been pigeon holed into one specific part of the stack and have no experience in the others. Is it like this at other FANGs?
