Spring planning, backlog grooming, etc. are not the examples I would use if I wanted to support the opinion that leetcode is not a real programming. (I definitely agree that some knowledge of algorithms and data structures can be very beneficial.)

My examples would be activities like building complex systems, maintaining and extending them, making them modular and flexible enough, doing performance analysis, identifying risks, and addressing technical depts, considering and implementing different architecture patterns, creating efficient CI/CD pipelines, automating routine.
