0-40: Major transitions
0 (Totally dissimilar): These roles exist on completely different planets—different functions, industries, and success metrics. Think switching from accounting to creative writing.
20 (Tangential overlap): You'll find a few shared tasks or tools, but this still feels like a major career pivot. Maybe you're moving from sales to product management—some skills transfer, but it's definitely a big shift.
40 (Distant cousins): Still a transition, but you're staying within the same broad constellation. Picture moving from marketing to product roles—different responsibilities, but you're operating in related territory.
50-60: Manageable shifts
50 (Kindred, one step removed): This is where things get interesting. The roles are fairly similar, with perhaps one significant change in function, industry, or level—but not all three at once. You might be moving from marketing manager to product manager, or staying in product but switching industries.
60 (Solid Resemblance): You're looking at either the same sector with new responsibilities, or a different sector doing a familiar job. The core of what you do stays consistent, but the context changes.
80-100: Familiar territory
80 (Near-twin): Essentially the same role with just one or two headline differences. Maybe it's a scope change, different title, new region, or slightly different responsibilities, but the fundamental job remains the same.
100 (Exact match): Perfect alignment with your declared target role—same function, industry, seniority level, and mandate. This is exactly what you said you wanted.
