Is my timeline OK? How long should I plan for to reach my goal? Can I reach a goal in a month?
How long a mentorship is productive for is highly influenced by the goal you'd like to reach. Helping you wrap your head around a certain topic might take a month or two, going for an entirely different career is a matter of a year or more.
At MentorCruise, we learned that having a timeline in the first place is a good thing to have. We also learned that with a timeline of under a month it's difficult to build a fruitful relationship.
Today, we see an average duration of 3.5 months from start until end of a mentorship. Reaching a goal doesn't mean that a mentorship needs to end though, it's just the nature of a mentorship that changes.
