No card. Twenty minutes. A written report at the end.

What you walk away with

The report, in full.

Every session ends in writing: an overall score, the rubric dimension by dimension, and the exact moments to fix. This is what one looks like.

7.4/ 10
Overall
Problem-solving
8Two clarifying questions, then a clean plan before any code.
Communication
7Thought out loud through the approach; went quiet mid-implementation.
Correctness
9Working solution on the first pass; empty-day case handled.
Complexity
8O(n) time, O(24) space — stated, correct, slightly hedged.
Edge cases
5Ties and empty input surfaced only after a nudge.
What you nailed
—Clarified sortedness and input range before proposing a plan.
—Named the fixed-bucket tradeoff unprompted.
What to improve next time
—You went quiet while coding — narrate the loop invariant as you write it.
—Volunteer edge cases before you’re asked: empty input, ties, the midnight boundary.
—Commit to the complexity answer, then justify it — hedging reads as uncertainty.
What it is

A real interview, on demand.

Not a judge, not test cases — an interviewer. It withholds the spec until you ask, probes your tradeoffs, stays quiet while you code, and asks for the complexity before writing you a report scored against a fixed rubric. Voice or text, your pick.

How a session goes
01
Clarify
Constraints, edge cases, input scale. Nothing is volunteered.
02
Approach
State a plan and the tradeoff before a line is written.
03
Code
The editor is shared. The interviewer reads as you type.
04
Complexity
Time, space, and what you'd change with ten times the data.
05
Feedback
A written report against the rubric — never spoken.
