I had a new VP start and immediately was DMing me on slack asking for details on every thread i was in.
3 months in and continues the trend but then started having 1-1s with my team to further get details and question the decisions being made
6 months in I had a talk wiht him about this level of micromanagement as it still had not changed and it was all "I have no idea" "I don't feel like i'm being that bad" "I don't agree"
7 months in I'm looking for a new job and his boss is asking "why" after i informed him since the interview and constantly over the last 6 months that I could tell he was a micromanager type
More than math courses - logic courses in general helped me rethink and structure things in a variety of ways in how to approach problems. If nothing else it improves your "if-then-else"-fu to understand when you are not(not(not something))). My math degree required logic courses though at the same time so it made sense. For higher level math logic plays a heavy role and so leveraging that aspect helps in a lot of ways.
