IQB Interview Question Bank: Coding Practice Guide

January 26, 2026(Last edited on: September 30, 2026)By Beyz Editorial Team

What is the IQB interview question bank?

IQB (Interview Question Bank) is a public site that aggregates real interview questions and organizes them by company and position. The homepage advertises a daily‑updated database and free sign‑up with full access to view and download question sheets, often as Excel files, across tech, finance, and consulting roles IQB Interview Questions Bank. As of the page’s stated update time, it lists overall counts (for example, “144,263 Total Questions” and “1,037 Total Companies”), but those numbers can change as the database updates IQB Interview Questions Bank.

Direct answer: Use IQB to quickly retrieve a targeted set of company/role‑relevant questions, then run a repeatable loop—timed attempt, review with a rubric, and scheduled redo. IQB is the retrieval layer; your practice environment (editor, platform, or assistant) is the execution layer.

Fast start: Turn IQB into a structured coding practice system

Here’s a simple, repeatable setup that works whether you have 5 hours a week or just a few short blocks. The goal is fewer, better‑chosen questions and a tighter review loop.

Define one scope for the week

Job family and level (e.g., Backend SWE, mid‑level)
Target companies (1–3 you’re actively interviewing with)
Round type (coding; add system design or behavioral if needed)

Retrieve 8–12 prompts in 10 minutes

On IQB, browse by company and position to pull a small, coherent set. The site shows “Interview Position” and “Company” groupings and offers downloadable sheets, often as Excel, after sign‑in (advertised as 100% free) IQB Interview Questions Bank.
If you’re early in prep, bias toward common patterns (arrays/strings, hashing, trees/graphs, BFS/DFS, two‑pointers, simple DP). If you’re later, bias toward your weak patterns.

Run timed attempts

Short timer beats long marathons: 20–30 minutes per coding problem is enough to surface gaps.
Before code: restate constraints, name your likely pattern, and call out two edge cases. Then implement and verify time/space complexity.

Review with a rubric

Grade yourself on four things: pattern choice, implementation correctness, edge‑case coverage, and explanation clarity.
Write one sentence per miss: the mistake, the fix, the trigger (e.g., “I rushed when it looked easy”).

Schedule redos

Redo the same set 2–3 days later. Change only the timer or constraints to avoid memorization. Add new questions only when redo accuracy and explanation quality stabilize.

Build a targeted set (step‑by‑step)

Use this mini‑workflow to go from browsing to a practice set fast:

Pick 2 companies you care about now and 1 “stretch” company.
From IQB, grab 3–4 coding questions per company that map to the same 3–4 patterns; favor recency when listed and match the role (e.g., Backend vs. Frontend) IQB Interview Questions Bank.
Add one system design and 2 behavioral prompts if your loop includes them; keep everything in one small set for the week. If you want structured behavioral prompts to reuse across companies, see Behavioral Interview Question Bank: Build & Reuse (https://beyz.ai/blog/behavioral-interview-question-bank-build-once-reuse-everywhere). For system design, see System Design Question Bank: Prompts + Answer Framework (https://beyz.ai/blog/beyz-system-design-question-bank).

Where IQB sits in a modern practice stack

Think of three layers:

Question bank (selection): IQB advertises daily updates, company/position groupings, and downloadable sheets to assemble sets quickly IQB Interview Questions Bank.
Practice surface (execution): your IDE, whiteboard app, or a coding platform. Timers and test‑case discipline matter more than which editor you use.
Coaching and review (feedback): a rubric, peer/mocks, or an assistant.

If you prefer an assistant in practice mode, Beyz offers a Coding Assistant that the vendor says can break down logic, analyze time/space complexity, and craft solutions; it’s part of a suite that also includes Solo Practice and role‑tailored Interview Cheat Sheets AI Interview Assistant | Beyz AI Coding Assistant Solo Practice Interview Cheat Sheets. Treat these as scaffolding for structure and explanation—not as an auto‑solver during interviews.

If you want a browseable Q&A complement by company and role, Beyz also maintains an Interview Questions & Answers hub with company‑specific entries and role groupings Interview Questions & Answers.

Company‑specific practice without overfitting

Company tags are a compass, not a prediction. Use them to select patterns and difficulty bands that show up repeatedly for your role. Avoid two traps:

Overfitting to a unique prompt from a single report
Mixing incompatible scopes (e.g., SRE vs. Android) in the same week

A practical approach:

For each target company, list 3 recurring patterns (e.g., graph traversal; heap scheduling; string normalization). Ensure at least two questions per pattern in your set.
For each question, note the constraint that drives the solution (n ≤ 10^5 implies O(n log n) or O(n) only; streaming implies memory bounds). Then force yourself to say the constraint aloud at the start of each attempt.

Review mechanics that actually stick

Complexity first: Before coding, state the target time/space in one sentence. After coding, restate what you achieved and why.
Edge‑case sweep: Run 5 quick tests—empty/single, min/max constraints, duplicate elements, sorted/unsorted, and adversarial inputs. For a compact checklist to say out loud, see Coding Interview Edge‑Case Checklist (https://beyz.ai/blog/coding-interview-edge-cases-30-to-say-out-loud).
Redo cadence: If you miss a pattern twice, schedule it twice next week. If you pass twice comfortably, graduate it and pull a fresh prompt for the same pattern.

Optional tools for solo practice

If your goal is to rehearse with the same structure you’ll use later, Beyz’s Solo Practice runs in the same context as its live assistant, according to the vendor AI Interview Assistant | Beyz AI Solo Practice.
Beyz also advertises Screen Solver, which can answer on‑screen questions in “Coder” and “Solver” modes. It’s positioned as an invisible overlay that stays undetectable to screen sharing/recording per the product page Beyz Screen Solver. Use assistants ethically—great for self‑study and post‑practice debriefs; do not rely on them during assessments or interviews.

FAQ

Is IQB really free? The homepage states “Totally FREE,” with sign‑up for full access to view and download question sheets, and it emphasizes daily updates IQB Interview Questions Bank.
Can IQB predict the exact questions I’ll get? No bank can guarantee that. Treat company/position labels as a way to focus on recurring themes and difficulty, not as a leak of the exact prompt. Build mastery of patterns and constraints, then practice explaining trade‑offs.
Can I export or download questions for offline study? The site repeatedly shows “Get Excel” for many entries and notes that members can download question sheets IQB Interview Questions Bank.

Next step

Pick one role and one target company, pull 8–12 IQB questions into a set, and run the loop this week: timed attempt → rubric review → spaced redo. If you want structured help during practice, try Beyz’s Coding Assistant or Solo Practice alongside your editor Coding Assistant Solo Practice.
