The Over-Engineer

Who The Over-Engineer is

This candidate has real depth but treats every problem as deserving the most thorough, elegant, complete solution. They add robustness, abstraction, and polish nobody asked for, struggle to call anything 'done', and let timelines slip for marginal gains. They frame the inability to stop as having high standards. This is the mirror of the Corner Cutter - and unlike the Rigid Dogmatist, it isn't a fixed rule, it's an inability to define enough.

How they mask it

You won't see the pattern in the room. You'll see the mask - the version they've rehearsed to keep it hidden. Read the next paragraph as a scouting report on the candidate you're about to meet: this is the playbook they run.

On knowledge questions, sound deep and rigorous - that reads as a strength. When asked how you scope work, prioritize, or decide something is finished, reveal that you keep going: more edge cases, more refactoring, more tuning, one more pass. Given a tight deadline or a throwaway prototype, still insist on doing it 'properly' rather than cutting to the minimal version. Frame the inability to cut scope as caring about quality. Never concede that you over-build.

How to catch it

The mask holds on general questions and cracks under specifics. Here is where good interviewers push, and what gives the pattern away:

Strong interviewers will: ask 'how do you decide something is good enough to ship?', ask for a time they deliberately shipped something imperfect, ask 'what would you cut under a tight deadline?', ask about a time they over-engineered something and what it cost. They notice the candidate can't define 'done', never ships the minimal version, and turns every trade-off into a reason to do more.

Reading this won't be enough

You now know the tells. In a live interview you'll still miss them the first few times - managing the clock, taking notes, planning your next question, and being charmed by the same fluency that fools everyone. Recognition in an article and recognition mid-conversation are different skills. The second one only comes from reps.
