01
Three problems, or one problem and two weak spots
Written in the morning and kept small enough that a tired evening after work still clears them.
why prep drifts
Nothing is due, so nothing is ever late
- 01
Preparation without a date has no edge
Two weeks pass in which you meant to do problems and can name none that you did, and nothing anywhere recorded that.
- 02
A rejection takes the next three days with it
The bad screen lands, practice stops exactly when it mattered, and the hole in the schedule is invisible until the next interview.
- 03
Problem counts flatter you
A solved total measures what you enjoyed, not what you avoided. From inside, nineteen days out of thirty and six days out of thirty feel much the same.
the loop
Three tasks, one report, repeat for a hundred days
02
Log what you actually opened
Two lines at night, including the topic you swerved again. Patterns you would never notice show up by day thirty.
03
Practise where the gaps are visible
Everyone reports the same way. Skipping the topic you hate stops being a private arrangement with yourself.
how it tends to go
A hundred days of prep with no interview booked
log
Finding a daily size that survives a workday. Usually smaller than the first version you wrote down.
Day 1–10
Finding a daily size that survives a workday. Usually smaller than the first version you wrote down.
Day 30
The stretch where nothing is scheduled and the motivation is gone. The log is what stops the days from vanishing.
Day 100
A hundred entries showing what you practised, what you dodged, and how long you kept going.

before you sign up
The obvious questions
Will this get me an offer?
No, and anyone promising that is guessing. This holds whether the practice happens. The interview is still yours.
Do you set the problems?
No. Use whatever platform you already pay for, or one you don't. We never see your solutions.
Is mock interviewing included?
Not as part of the mechanism. People in the group pair up for it on their own fairly often.
What if I get an offer on day 40?
Then the remaining days are yours to redirect, or to stop. Nobody holds you to a hundred.
What does it cost?
The price is published when the group opens. Nothing is charged here.
The interview date arrives whether the practice happened or not
