Spaced Repetition for Investment Banking Interview Prep: Remember Technicals Under Pressure
Spaced repetition means reviewing a question right before you would forget it, at growing intervals: a day later, about a week later, then longer. It is the most efficient way to keep dozens of technical concepts ready at once, which is exactly what a banking interview asks of you.
Why cramming fails in technical interviews
Most candidates study a topic until it feels solid, then move on. A week later, the DCF they knew cold is fuzzy again. That is normal: memory fades quickly after you first learn something, and much of it is gone within days unless you revisit it.
Interviews make this worse because they are cumulative. A first round can jump from accounting to an LBO to a merger model in ten minutes. You need every topic ready at the same time, not just the one you studied last.
How spaced repetition works
Each time you answer a question, the next review is scheduled based on how well you did:
| How you answered | Next review |
|---|
| Missed it or said "I don't know" | Tomorrow, and the streak resets |
| Got it right the first time | In 1 day |
| Got it right the second time | In about 6 days |
| Keep getting it right | Interval keeps growing, faster for confident answers |
Questions you find easy fade into the background. Questions you struggle with come back often until they stick. Your study time goes where it is actually needed.
Spaced repetition with an interview date
Standard spaced repetition can push a mastered question weeks out. Before an interview, that is a problem: you do not want a concept scheduled to come back after the interview has happened. ApexIB caps every interval so reviews always land before your interview date, and leans harder on review over new material as the date gets closer.
How Daily Review works in ApexIB
- Every graded practice answer updates that question's schedule.
- Your dashboard shows a Daily Review card with how many questions are due now and how many are coming up this week.
- One tap starts a session made only of due questions, oldest first, each labeled with why it is back.
- When you are caught up, the card tells you when the next review is due, and regular practice continues with new material.
A simple daily routine
10 minutes: clear your due reviews.
20 minutes: new questions in your weakest topic.
Once a week: a mock interview to test everything together.
Consistency matters more than session length. Twenty focused minutes every day beats a three-hour cram on Sunday.
Frequently asked questions
Does spaced repetition work for finance technicals?
Yes. Technical interview questions are a large set of concepts you need to recall and explain on demand, which is exactly the problem spaced repetition is designed for.
How many review questions should I do a day?
Clear whatever is due. For most candidates that is 5 to 20 questions a day, which takes about 10 to 15 minutes.
What if I miss a few days?
Overdue questions simply wait in your queue, oldest first. Clear them over the next couple of days rather than all at once.
Is spaced repetition enough on its own?
No. It keeps what you have learned fresh. Pair it with new material in weak topics and regular mock interviews to practice explaining under pressure.
