Coding questions
Practice problems with approaches.
How to Prepare for Twitter (X)
X engineering interviews still expect strong DSA and systems sense for many roles. Prep coding seriously; culture questions vary by team.
What x actually tests
Section titled “What x actually tests”First round: X (Twitter) coding interviews
Time split that matches how candidates report outcomes (not a marketing pie chart):
- DSA 50%
- CS + projects 25%
- Behavioral 15%
- Mocks 10%
Patterns are from student reports and vary by role and drive. Trust your college placement email over blog folklore.
Hiring flow you should prep for
Section titled “Hiring flow you should prep for”| Stage | Time | What they check |
|---|---|---|
| Screens | timed | Coding |
| Loops | multiple | DSA/systems + behavioral |
Time allocation
Section titled “Time allocation”- Data Structures & Algorithms (40% time) - Master arrays, strings, trees, graphs, dynamic programming, practice 200+ LeetCode problems
- System Design (25% time) - Learn distributed systems, scalability, databases, caching, load balancing
- Coding Practice (20% time) - Solve medium-hard problems on LeetCode, HackerRank, focus on optimization
- CS Fundamentals (10% time) - Review OOP, DBMS, OS, Networking basics
- Behavioral Preparation (5% time) - Prepare for HR and behavioral rounds
Daily loop (75-120 minutes)
Section titled “Daily loop (75-120 minutes)”- One timed block that matches X (Twitter)’s first round (coding OA)
- Log misses: topic + why you failed (speed, concept, carelessness)
- Re-solve yesterday’s misses cold
- Twice a week: 10 minutes of resume/project narration out loud
8-Week product-company plan
Section titled “8-Week product-company plan”| Week | Focus | Exit criteria |
|---|---|---|
| 1-2 | Core DSA (arrays, hashing, strings) | Timed easy→medium comfort |
| 3-4 | Trees, graphs, recursion | Explain traversals + complexity |
| 5-6 | DP + company-flavored mocks | 2-problem mock passes |
| 7 | Projects + CS fundamentals | Resume bullets defended |
| 8 | Behavioral + polish | No new topics; only closure |
Round-by-round strategy
Section titled “Round-by-round strategy”Online Assessment
Section titled “Online Assessment”- Order problems by confidence after a 3-4 minute skim
- Passing test cases beats a brilliant half-solution
- Invent edge cases before submit; watch timeboxes
Technical interviews
Section titled “Technical interviews”- Restate → brute force → optimize → code → test
- Defend edge cases and code clarity.
- Tie CS answers to a project when it strengthens the point
HR / managerial
Section titled “HR / managerial”- Why X (Twitter), why this team/role, location flexibility
- STAR with a metric; pick 2-3 real company values and prepare proof
X -specific drills
Section titled “X -specific drills”- Medium-hard DSA
- Distributed systems basics for experienced tracks
Topic checklist
Section titled “Topic checklist”- Medium DSA fluency
- Clean code + edge cases
- OOPs + DBMS basics
- Measurable project stories
- Domain scenarios for this product
- API/design intuition at fresher depth
- Full-length mock every other day
- Light revision only - no new rabbit holes
- Sleep, ID proofs, machine/network checklist for test day
Final stretch
Section titled “Final stretch”30 days out: weekly full OA-style mocks; close weak DSA patterns; draft STAR stories.
7 days out: alternate mock / review days; re-solve misses cold; no new patterns.
Day before: skim notes, check machine/network/ID logistics, sleep.
Common mistakes for x aspirants
Section titled “Common mistakes for x aspirants”- Outdated ‘Twitter easy’ myths - expect real coding bars - fix this first
- Preparing only interviews while failing X (Twitter)’s first round
- Collecting notes without timed mocks
- Listing five frameworks on the resume and defending none
- Changing language/stack one week before the drive
- Domain buzzwords without engineering reasoning

Next step: Run one timed mock this week that matches X (Twitter)’s first round (coding OA), then build the weeks around your weakest section - not around what is most fun to study.
