Tailored for your role

Built for every kind of interview.

WispherFlow knows what your role gets asked. Sample questions and answer frameworks tuned for software engineering, product, design, sales, ML/data, and consulting.

Software Engineer

System design, coding rounds, behavioral loops. From new-grad to staff — ready for every interview format from Google to Stripe.

1,148 SWE offers landed

Sample question

“Implement a base62 URL shortener — show me the code.”

WispherFlow Answer0.6s

7-char base62 keys give us 62⁷ ≈ 3.5 trillion unique IDs. Hash from an auto-incrementing ID for monotonic, conflict-free generation:

import string

ALPHA = string.ascii_letters + string.digits  # 62 chars

def shorten(id: int) -> str:
    """7-char base62 key for an incrementing ID."""
    out = []
    while id:
        id, rem = divmod(id, 62)
        out.append(ALPHA[rem])
    return ''.join(reversed(out)).rjust(7, '0')

shorten(987654321)  # → "0aHkOR1"

AI Engineer

LLM apps, RAG systems, evals, prompt engineering. Production GenAI at scale — the hottest hiring track right now.

318 AI Eng offers landed

Sample question

“How would you build a production RAG system over 10M documents?”

WispherFlow Answer0.8s

Two-stage retrieval beats single-stage at this scale. Embed with bge-large or text-embedding-3, store in pgvector or Pinecone. Hybrid BM25 + dense retrieve top-200, rerank to top-10 with a cross-encoder:

# 1. Retrieve (hybrid)
candidates = bm25.search(q, k=100) + vector.search(q, k=100)

# 2. Rerank (cross-encoder)
top10 = reranker.score(q, candidates)[:10]

# 3. Generate w/ forced citations
answer = llm.complete(
    CITATION_PROMPT(q, top10),
    temperature=0.1,
)

# 4. Eval: RAGAS metrics
ragas.evaluate(answer, ["relevance", "faithfulness"])

ML Researcher

Model architecture, evaluation design, ML systems at scale. Paper depth on demand for research-track interviews.

148 ML offers landed

Sample question

“Explain attention, then how would you scale a transformer to 10× throughput?”

WispherFlow Answer0.9s

Attention computes pairwise weights via softmax over query-key dot products, then a weighted sum over values. For 10× throughput: KV-cache reuse across requests, FlashAttention-2 for memory-IO efficiency, tensor parallelism across 8 GPUs, and INT8 quantization on the inference path. Latency drops, batch utilization rises.

Data Engineer

Pipelines, warehouses, dbt, SQL deep-dives. Production-scale data work, including streaming and CDC.

412 Data offers landed

Sample question

“Write SQL to find the 2nd-highest salary per department, with dedupe.”

WispherFlow Answer0.5s

Window function with DENSE_RANK handles ties cleanly — that’s what “with dedupe” signals. Avoid LIMIT/OFFSET tricks which break with ties:

WITH ranked AS (
  SELECT
    department_id,
    employee_id,
    salary,
    DENSE_RANK() OVER (
      PARTITION BY department_id
      ORDER BY salary DESC
    ) AS rnk
  FROM employees
)
SELECT department_id, employee_id, salary
FROM ranked
WHERE rnk = 2;

Solution Architect

Multi-cloud architectures, enterprise integration, scale & cost trade-offs. Whiteboard fluency on demand.

234 Architect offers landed

Sample question

“Design a multi-region disaster recovery plan with RPO under 5 min.”

WispherFlow Answer0.7s

Active-active across 3 regions with Aurora Global Database — sub-second replication lag. Route 53 health-check failover routes traffic to surviving regions. Stateful data in DynamoDB Global Tables for write-anywhere durability. App layer in EKS with cross-region service mesh. Monthly chaos game-day to validate. Tested RPO 30s, RTO under 4 min.

Product Manager

Strategy frameworks, prioritization, case studies, and stories that close the loop on every PM round at FAANG and beyond.

624 PM offers landed

Sample question

“How would you redesign Instagram for kids under 13?”

WispherFlow Answer0.7s

Lead with safety: parental controls baked in by default, an under-13 age gate verified through the parent account, and feeds curated only from verified kid-safe creators. Monetization stays simple — zero ads under 13, only optional in-app purchases with explicit parental approval per transaction.

Designer

Portfolio walks, critique rounds, and design challenges. Speak fluently about your process under pressure.

287 Designer offers landed

Sample question

“Walk me through your design process for a complex feature.”

WispherFlow Answer0.8s

I start with JTBD interviews — at least five users to triangulate the actual job they hire the product for. Then competitive teardown, two divergent concepts, the PM and I pick one with rationale, then prototype in Figma. Final pass is always a 30-minute team critique before engineering handoff.

Sales & BD

Cold opens, closing scripts, objection drills. Every common sales-interview format covered, from SDR to enterprise AE.

193 Sales offers landed

Sample question

“Walk me through a competitive deal you closed.”

WispherFlow Answer0.5s

A $400K seat expansion against an incumbent. Their pitch was features; mine was workflow ROI. I led with three customer references in their exact vertical, then a 14-day shadow pilot with their lead engineer on the call. We closed at 12% over their bid because the buying committee already trusted the outcome.

Consultant

MECE structures, market sizing, case-cracking. Crisp frameworks delivered in real time across McKinsey, Bain, Deloitte loops.

293 Consulting offers landed

Sample question

“Estimate the market size for electric vehicles in India by 2030.”

WispherFlow Answer0.7s

Top-down: India’s auto market reaches roughly $120B by 2030. Government targets 30% EV penetration, so TAM lands around $36B. Bottom-up check: 1.4B population, ~10% earning above EV-affordability threshold, 70% urban, ~5% the new-car-buying segment — gives $32-40B. Frameworks agree at roughly $35B.

What candidates say

Real users, real offers.

“I’d gone through two rounds at this company over two years. Both times I blanked on behavioral. Third attempt I ran WispherFlow the whole loop. Something clicked. I stopped performing and started just talking. Offer by end of week.”

D.R. Backend Engineer · Stripe · March 2026

“LP rounds were always where I’d lose it. Go broad, get generic, watch the interviewer check out. Had WispherFlow running this time with a real story per principle, specific and tight. Walked out knowing I’d nailed it.”

R.K. SDE II · Amazon

“Three years as an IC, no PM title, applying senior. The experience was there but I kept losing it under pressure. WispherFlow kept me anchored mid-answer. I stopped second-guessing and it showed. Walked out feeling like I actually deserved the role.”

L.V. Senior PM · Meta

“The final round threw questions I’d genuinely never seen. Normally I spiral. WispherFlow gave me a direction in real time, I kept my pace and stayed coherent. Composure is half the score in a quant round. Crushed it.”

R.P. Quant Researcher · Citadel

“I had all the frameworks but kept losing the thread mid-case. With WispherFlow running I had an anchor every time I started to drift. Walked out of all three cases feeling in control. First time that had ever happened.”

T.O. Sr Consultant · Bain & Co

Frequently asked

Everything you wanted to know, asked already.

Quick answers on visibility, platforms, models, and what happens to your interview audio.

Which interview platforms work with WispherFlow?

All of them. WispherFlow captures audio from any source on your machine — Zoom, Teams, Meet, Webex, Slack Huddles, Discord, GoTo, BlueJeans, Whereby, or even a random conference link. No plugins, no extensions, no browser permissions required.

How does WispherFlow know my resume?

Upload your resume once (PDF or .docx) and WispherFlow indexes it locally. When a question comes in, the AI cross-references it against your actual projects, metrics, and language so the answer sounds like you, not a generic ChatGPT response.

What AI models do you use?

GPT-5, GPT-5 nano, Claude 4.6 (Sonnet + Opus), Gemini 2.5 Flash + Pro, Llama 4 Scout, and our own fine-tuned model for behavioral questions. We pick the best one per question type automatically, or you can override.

Is my interview audio stored?

No. Audio is processed in-memory and discarded immediately after the answer is generated. We don't keep recordings, transcripts, or logs by default. You can opt into local-only session logs for your own review.

What if the AI gives a wrong answer?

You see the answer before you speak — never repeat verbatim. WispherFlow is a copilot, not a script. For technical interviews, the AI shows citations to your resume so you can verify the claim is grounded.

Can I use it for coding interviews?

Yes. WispherFlow handles algorithm questions (LeetCode-style), system design, and language-specific deep dives. It can also pretty-print code answers in your preferred language — Python, JavaScript, Go, Rust, Java, C++, TypeScript, SQL.

Common Questions

Can my interviewer see WispherFlow?

No. In the browser, WispherFlow runs in a separate floating window that doesn't appear when you share your screen. The desktop app goes even further. Your entire WispherFlow window appears blank to all recording and screen-sharing tools. No one on the other end can see it.

Which interview platforms does it work with?

All of them. Any video call, phone call through speakers, or even an in-person interview picked up by your microphone. WispherFlow listens to the audio coming from your computer, so the specific platform doesn't matter.

What AI models can I use?

You choose your model before each session from a range of options including GPT-4o Mini, Claude Opus, Claude Haiku, DeepSeek R1, and more. Free trial and paid sessions let you pick any model. Practice mode uses a fast open-source model for instant, unlimited sessions.

Is my data stored or shared?

Audio is processed in real time and is not stored after your session ends. Your resume and job description are fully encrypted, both when stored and when transmitted. You can delete all your data at any time from Settings. We never share or sell your information.

Can I practice for free?

Yes. Practice mode is completely free and unlimited. It uses a fast open-source AI model for instant responses. Use it to get comfortable with the interface and test your setup before a real interview. No credits needed, no time limit.

What happens after my free trial session ends?

Your free trial gives you one full session with any AI model for up to 10 minutes. After that, you can continue practicing for free in practice mode, or purchase credits or a subscription for more sessions. Credits are measured per-minute and never expire.

Does it work for coding interviews?

Yes. Code Challenge Mode reads coding prompts and generates structured walkthroughs with step-by-step explanations. It works with any online coding platform or shared IDE.

How does credit billing work?

You only pay for the time you actually use. Every 30 minutes of session time uses half a credit, measured by the minute. If your session ends early, you keep the rest. Credits never expire. Buy once, use whenever you're ready.

What browser do I need?

WispherFlow works best in Chrome or Edge. These browsers fully support audio capture and the invisible floating window. Firefox and Safari have limited support. For the best experience and full invisibility, use the desktop app.

Security

Your Data. Your Control.

We handle sensitive career data. Here's how we protect it.
