## Frequently asked questions

**Is LeetCode enough for placements?**

For most placements, yes! LeetCode covers:
- DSA problems (sufficient for any company)
- Company-tagged questions (with Premium)
- Discussion forums for solutions

You may need additional resources for:
- Aptitude (service companies) - Use PrepInsta
- System Design (senior roles) - Use Grokking
- Theory concepts - Use GFG

**How many LeetCode problems are enough?**

Depends on target:
- **Service companies (TCS, Infosys)**: 50-100 problems
- **Good startups**: 150-200 problems
- **FAANG**: 200-300 problems

Quality matters more than quantity. Understand patterns, don't just memorize.

**Should I do competitive programming?**

**Pros**: Improves speed, problem-solving
**Cons**: Time-intensive, not directly tested

**Recommendation**:
- For FAANG: Optional (focus on LeetCode)
- For Google specifically: Helpful
- For service companies: Not needed

**HackerRank vs LeetCode - which first?**

**Start with HackerRank if**:
- Complete beginner
- Targeting service companies
- Want to build confidence

**Start with LeetCode if**:
- Have basic DSA knowledge
- Targeting product companies
- Comfortable with Medium difficulty

**InterviewBit vs LeetCode for 2026 placements?**

**InterviewBit** if you need a guided path from zero and campus timelines under ~3 months. **LeetCode** once you can solve Easy consistently - better volume, company tags, and contest pace for product / startup OAs in 2026. Common stack: InterviewBit (or GFG) for foundations → LeetCode Medium patterns → company previous papers on this site. Skip paying for both unless you specifically want Scaler-style mentorship.

**Best free LeetCode alternatives in 2026?**

Strong free stacks: **InterviewBit + GeeksforGeeks practice + HackerRank** for service-company aptitude/coding mix; add **CodeChef practice** only if you enjoy contests. None fully replace LeetCode’s Medium catalogue for FAANG-style drills, but they are enough for TCS/Infosys/Wipro-style coding rounds when paired with previous papers.

## Interviewbit vs LeetCode (2026 placement pick)
One decision most freshers still overthink:

| If you are… | Prefer first | Then move to |
|-------------|--------------|--------------|
| Starting DSA from scratch | **InterviewBit** (guided track) | LeetCode Easy → Medium |
| Targeting product / startup OA in 2026 | **LeetCode** (patterns + tags) | Company papers + timed mocks |
| On a zero budget | InterviewBit + HackerRank + GFG | LeetCode free daily |
| Short on time (< 8 weeks) | Topic lists on InterviewBit/GFG | Only high-frequency LeetCode patterns |

Do not collect five Premium subs. One structured beginner path + one problem volume site beats tool-hopping.
