🎯 Python interview prep
Python interview prep — patterns, not problem-grinding.
104 interactive lessons: LeetCode patterns in Python + system design (Twitter, Uber, Stripe) + STAR behavioral. From junior loops to FAANG senior interviews. Built so you recognize the pattern, not just memorize the answer.

What you'll cover
Big-O & easy patterns
Time + space complexity from first principles, then the patterns that show up in EVERY junior-loop screening: two-pointer, sliding window, binary search, hash-set deduplication. Each pattern shipped with 3 worked examples + 2 self-quiz problems.
Arrays, strings, two-pointer
The bread-and-butter of phone screens. Reverse string in place, longest substring without repeats, two-sum / three-sum, container-with-most-water, valid palindrome with whitespace. Every solution timed against Big-O expectations.
Trees + graphs + BFS/DFS
Recursive vs iterative tree traversal, BFS shortest path, DFS connected components, topological sort for build-order interview questions, Union-Find for friend-network puzzles. Ends with a full graph-clone walkthrough.
DP + heap + tries
Dynamic programming: when to memoize, when to tabulate, why most DP is just 'remember the recursion you already did'. Heap patterns (top-K, merge-K, scheduler). Tries for autocomplete + word-search puzzles.
System design + STAR behavioral
L4/L5 interview prep: design Twitter feed at 100K req/s, Uber dispatch, Stripe webhook retry pipeline, Netflix recommendation cache. Plus 20+ STAR (Situation-Task-Action-Result) story templates for the behavioral round.
Concurrency / OS / ML interview topics
GIL questions you'll actually get asked, async vs threading trade-offs, lock + mutex puzzles, ML system design (feature stores, A/B testing infra). Capstone: a full 60-minute mock onsite — coding + system design + behavioral, graded.
Questions
How is this different from grinding LeetCode?
LeetCode has problems; we have problems + the pattern behind them + when to recognize it in a fresh question. After three dozen LeetCode problems most candidates can solve those three dozen problems. After our pattern-first track most students recognize the pattern in problem 31 and solve it cold.
Does this prep me for FAANG?
Yes — the system design module covers the 5 most-asked FAANG L4/L5 questions (Twitter feed, Uber, Netflix, Stripe webhooks, Calendly race conditions). The behavioral module has STAR templates calibrated to FAANG leadership-principle questions. Combine with the Senior Deep-Dives track for L5/staff signal.
Can I prep without Foundations?
If you've been writing Python for 6+ months, skip Foundations and start here. If you're a true beginner — finish Python Foundations first (15 lessons are free, no signup). Interview Prep assumes you read Python without translating it.
How long until I'm interview-ready?
60 days of focused work for an experienced backend dev preparing for a senior loop. 90-120 days for a career-switcher coming off Foundations. We don't promise an offer in N days — we DO promise you'll know the patterns to spot the question.
Is there mock-interview support?
Yes. Every module ends with a self-timed challenge. The final capstone is a 60-minute mock onsite — code + system design + STAR — with rubric grading from the AI tutor. For human review of your portfolio + LinkedIn, email support@learnpython.academy.
