My Dad worked for Alcatel-Lucent when they got bought out by Nokia, which is when I found out it’s apparently pronounced “Noy-kia” and not “No-kia” like I thought it was for the longest (or else my Dad was just mispronouncing it). I’m sure there was some big changes he saw, but he pretty much worked from home the entire time, so it wasn’t a big transition that we saw, he just did the same old job, though I think they did move their actual offices from the East side of town to the North-west. He worked with them up until 2019 when he retired.
