Netflix coding interview prep
Senior-heavy loops where judgement matters more than puzzle speed.
What the loop actually looks like
Netflix hires senior and expects senior behaviour: fewer algorithmic puzzles, more realistic problems and conversation about trade-offs, ownership, and impact. Coding rounds exist, but the bar is 'can you build and reason about real systems' rather than 'can you solve this in 20 minutes'.
What they reward
- Practical, realistic problems over contest-style puzzles
- Trade-off reasoning and system judgement
- Culture-fit depth — the memo is taken seriously
- Clear communication with senior peers
Patterns to drill first
Problems worth your time
In priority order. Open one to read the approach, or generate an interactive lesson and watch it run.
Merge IntervalsSort by start, then merge any interval that overlaps the last one kept.
Medium
Top K Frequent ElementsCount, then select the k largest — a heap or bucket sort beats a full sort.Medium
Find Median from Data StreamBalance a max-heap of the low half against a min-heap of the high half.Hard
Subarray Sum Equals KA subarray sums to k when a previous prefix equals current prefix minus k.Medium
Meeting Rooms IIThe peak number of simultaneous meetings is the number of rooms needed.Medium
Longest Consecutive SequenceOnly start counting from a number that has no left neighbor.Medium
Tips specific to this loop
- — Read the culture memo properly — it genuinely drives the interview.
- — Lead with trade-offs and why you'd choose one design over another.
- — Expect fewer, longer conversations rather than a battery of quick problems.
