Scorecard — System Design Mock

Copy into sessions/<date>-<id>-<slug>/scorecard.md and fill. Mirrors guides/interviewer-guide.md §7.

   
Candidate  
Date  
Question (bank ID + title)
Calibrated to (company · level — senior · staff · principal · em · senior-em · director)
Kind / domain (Build · Review · Strategy / domain tag)
Attempt (N on this question · N overall)
Mode / pace / difficulty  
Elapsed (actual, from the shell — not the budget)

Scale: 1 below bar · 2 approaching · 3 at bar (hire) · 4 above bar

Every score carries evidence — a verbatim quote or a §10 timestamp. A dimension that was never probed is unscored (—), never a default 2. A wall of 4s means the interviewer under-probed and the sheet should say so.

Scores are against the target level’s bar. Weights (H 1.5 · N 1.0 · L 0.5) come from levels.md §2 for that level.

# Dimension Weight Score Evidence (quote / timestamp)
1 Requirements & scoping      
2 Estimation (drives decisions)      
3 High-level design      
4 Technical depth (deep dive)      
5 Trade-off reasoning      
6 Operations / reliability / cost — manager bar      
7 Communication & collaboration      
8 Handling ambiguity & pushback      
9 Leadership signal — technical (IC) or org/delivery (manager)      

Weighted score = Σ(weight × score) ÷ Σ(weight), scored dimensions only: ____ / 4 (show the arithmetic)

Outcome at the target level (levels.md §4: ≥3.25 strong hire · 2.75–3.24 hire · 2.25–2.74 lean no · <2.25 no hire; a 1 on any H-weight dimension caps it at lean no):


Help needed

Rung Count Where
(a) re-ask the requirement    
(b) narrow the area    
(c) name the tension    
(d) offer a binary choice    
floor hit — could not proceed without the answer    

Only (a)-level nudges → scoring well. Needing (d) to move at all → not at bar.

Overall help: ☐ none ☐ light nudges ☐ frequent steering ☐ interviewer led throughout


Time management

☐ finished cleanly ☐ rushed the end ☐ ran out of time ☐ finished early with room to spare

Where the time actually went (from §10 timestamps, vs budget):

Phase Budget Actual Note
1 Requirements      
2 Estimation      
3 High-level design      
4 Deep dives      
5 Wrap      

The curveball

What was thrown, when:

Reaction — calm/frozen/defensive · revisited only the affected part or rebuilt everything · did they say what it cost:


The delta vs the cue sheet

In the checklist, not raised by the candidate — and, honestly, which of these actually mattered versus which are checklist noise:

Item Mattered? Why
     

Raised by the candidate, not in the checklist (these are often the 4s):

Verdict

Top 2 strengths, each with a quote:

1. 2.

Top 2 things to improve, each with the moment it showed up:

1. 2.

One drill for next time (exactly one, small enough to do this week):

Overall: ☐ strong hire ☐ hire ☐ mixed / lean no ☐ no hire

Apparent level: ☐ senior ☐ staff ☐ principal ☐ em ☐ senior-em ☐ director — and in one line, where it differed by dimension (e.g. “staff depth, senior framing”)

Self-assessment accuracy (what they said at debrief step 1 vs what the sheet says — a strong signal in its own right): ☐ accurate ☐ too harsh ☐ too generous


Interviewer self-audit

Honesty here protects the value of every score above.

  • Leaks (components named before they named them, praise given mid-round, leading questions):
  • Probes I should have asked and didn’t:
  • Did I under-probe or over-help?
  • Dimensions this session genuinely could not measure:
