Balancing a Full-Time Job with Interview Prep
How to grind LeetCode without getting fired or divorced.
The "standard" advice for interview prep is insane: "Just do 3 hours of LeetCode a day and 5 hours on weekends."
If you have a full-time job, a family, or a pulse, this is a recipe for burnout.
You cannot train like a college student when you are a working professional. You need a different strategy.
The "Morning Power Hour"
Do not study after work.
After 8 hours of coding for your boss, your brain is mush. Your willpower is depleted. You will stare at the screen, get frustrated, and quit.
The Strategy: Wake up 1 hour earlier.
- 6:30 AM - 7:30 AM: Deep work.
- Your brain is fresh. The house is quiet.
- Do 1 medium problem. If you can't solve it, read the solution.
- Consistency > Intensity. 1 hour a day for 3 months is infinitely better than 8 hours on Saturday (which you will skip because you're tired).
The "Lunch Break" System Design
System Design doesn't require an IDE. It requires thinking.
- Use your lunch break to watch one system design video (YouTube or a course) or read one chapter of a book.
- Take notes on your phone.
- This keeps the concepts fresh without requiring deep focus.
The "Weekend Mock"
Save your weekends for the heavy lifting: Mock Interviews.
- Saturday morning: Do one full 45-minute mock interview (Pramp, friend, or AI).
- Saturday afternoon: Relax.
- Sunday: Rest.
Stop "Stealth Studying" at Work
Don't try to do LeetCode on your second monitor while your boss is talking.
- It creates anxiety (fear of getting caught).
- It ruins your performance at your actual job (which you need).
- It prevents deep work.
The Timeline
Accept that it will take longer.
- Unemployed student: 4 weeks prep.
- Full-time employee: 12-16 weeks prep.
Set your expectations accordingly. You are running a marathon, not a sprint.
