Compounds need longer
Multi joint lifts tax your whole system, so full recovery of 2 to 3 minutes lets you match or beat your reps on the next set. Research shows longer rest on compounds produces more total volume and more growth than rushing.
Rest 2 to 3 minutes on heavy compounds and 60 to 90 seconds on isolation work, longer when strength is the goal.
Rest 2 to 3 minutes between heavy compound sets like squats, deadlifts, bench, and rows so strength and form recover. On isolation moves like curls, lateral raises, and leg extensions, 60 to 90 seconds is plenty. Cutting rest too short on big lifts drops your reps and total load, which shortchanges growth.

Small muscle single joint work like biceps and side delts bounces back quickly, so 60 to 90 seconds keeps the session tight without hurting output. If your next set drops several reps, rest a bit longer.
The real rule is rest until you can hit your target reps again. If you are still breathing hard or the muscle feels flooded, give it another 30 seconds rather than forcing the next set.
