I remember the night before my first big system design interview. I was swamped with contradictory advice, barely slept, and scoured sites offering mock problems and courses. Somewhere in that midnight chaos, I stumbled upon Interview Query. The question I had then was simple but crucial: Is Interview Query worth it?
After six months of hands-on use, multiple interview rounds, and mentoring juniors who used it too, I’m finally ready to share my verdict, the lessons I learned, the engineering insights gained, and how it ranks in your prep arsenal.
What is Interview Query? (Quick Overview)
For those new to it:
- Interview Query is a platform focused on data science and software engineering interview prep.
- It offers a curated collection of interview questions, real-world case studies, detailed solutions, and even video explanations.
- Their focus often leans towards system design, machine learning, and datastructures; popular areas in tech interviews today.
(Pro tip: If you want a broader range of topics, pairing it with platforms like Educative’s System Design Course or ByteByteGo is a smart move.)
Personal Story: My First Encounter with Interview Query
When I was prepping for a mid-level tech role at a FAANG company, I was overwhelmed by the sheer volume of learning materials available. I had previously failed two phone screens because I couldn’t articulate structuring complex data problems.
Enter Interview Query.
- I started with their data science interview deck.
- The clarity of problem breakdowns and stepwise solutions felt different, more concise, more actionable.
- Their questions were a blend of classical and modern challenges, like handling real-time recommendation systems or addressing data skew in pipelines.
(Lesson: Clear, teachable breakdown trumps linear question banks. Even if you skim, you’ll get value.)
3. What Makes Interview Query Stand Out? (And Where It Falls Short)
Strong Points:
- Curated real-world problems: It’s not just textbook-like questions, but practical scenarios that mirror actual challenges at big tech.
- Stepwise solutions: Many platforms overwhelm you with code dumps. IQ focuses on explaining why a solution works.
- Machine learning + data science focus: If your target role emphasizes these skills, it’s gold.
- Community and Q&A: You can engage, ask clarifications, and sometimes get insider tips from other candidates.
Limitations:
- Niche scope: For purely software engineering roles without data science, it might feel limited.
- Pricing vs breadth: Interview Query’s subscription is not cheap ($49/month or discounted yearly). If you’re short on time or money, consider judging if the data science focus aligns with your goals.
- UI and UX: The interface can feel a bit barebones compared to slick platforms like DesignGurus.io. But functionality wins over aesthetics.
4. Engineering Tradeoffs I Noticed Using Interview Query
Every tool brings an opportunity, but also a tradeoff.
| Tradeoff | Observation | What I Did |
|---|---|---|
| Depth vs breadth | IQ is deep in data science but narrower in software design | Supplemented with Educative and LeetCode |
| Reading vs Hands-on | IQ’s explanations are strong, but coding practice is lighter | Paired with platforms offering coding challenges |
| Theory vs Practical | Real-world cases enhanced my thinking, but didn’t replace algorithm drills | Balanced IQ with daily algorithm practice |
(Visual Callout: If you want a balanced prep architecture, I suggest:
Interview Query + Educative (for system design) + LeetCode (algorithms))
5. Real Interview Impact: Did Interview Query Help Me Land an Offer?
Short answer: Yes, but it wasn’t magic.
Here’s how Interview Query truly helped:
- Structured thinking: Their problem explanations taught me to break down complex cases logically, something interviewers consistently praised.
- Confidence in ML concepts: When asked about handling skewed datasets or model evaluation metrics, I was ready.
- Storytelling in answers: Their “why” focused solutions helped me narrate my logic rather than just reciting memorized templates.
But note:
- Interview success comes from practice and mindset. IQ was my guide, not my crutch.
- I still had to put in hours on algorithm sites to nail coding rounds.
(Lesson: Use IQ as your blueprint, not the entire house.)
6. How I Integrated Interview Query into My Prep Routine
Here’s a rundown of how I balanced IQ and other resources:
- Morning: 1-2 IQ case problems with deep reading.
- Afternoon: Coding challenges on LeetCode or HackerRank.
- Weekly: Watch system design videos on ByteByteGo or take Educative courses for big-picture concepts.
- Discussion: Participate in mock interviews or peer discussions in IQ’s community channels.
(Pro tip: Journaling your progress helps. After each IQ question, write down:
- What concepts did I learn?
- What was confusing?
- How would I explain this in an interview?)
7. Tips for Getting the Most Out of Interview Query
- Don’t rush: Digest problems slowly. Quality beats quantity.
- Focus on explanation: Make sure you understand why a solution works, not just the code.
- Use filters: IQ lets you filter questions by company and difficulty. Target your dream companies’ question sets.
- Write practice answers: Try explaining your approach aloud or on paper before coding.
- Leverage community: Ask questions if stuck. The discussions often reveal alternative approaches.
Final Thoughts – Is Interview Query Worth It for You?
If you’re targeting data science or ML-heavy software roles, Interview Query is a highly valuable investment. It bridges the gap between theory and practical engineering challenges effectively.
However, as a standalone resource for general software engineering or system design, it falls short without complementary platforms.
Remember:
No course or tool guarantees success. It’s the consistent, deliberate effort you put in daily that moves the needle.
You’re closer than you think. Use the right tools, build your frameworks, and learn from each experience, as I did with Interview Query.
