interview-prep

An interview-preparation guide that collects candidate experiences from Glassdoor, Blind, and Reddit. These are websites where people share job interview questions and experiences.

In plain words
What is it for?
Use it to prepare for interviews at a specific company, including software engineering, data science, or other roles.
Why use it?
It helps replace guesswork with repeated questions and patterns reported by candidates. The guide can be tailored to a company and, optionally, a job role.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

interview-prep scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Interview Prep Guide Generator

Given a company name (and optionally a role), scrape real interview experiences from Glassdoor, Blind, and Reddit simultaneously — extract repeated questions, identify patterns, and return a structured prep guide based on what actually happens in the room.

Step 1 — Clarify inputs

You need:

  • Company name — e.g. "Google", "Stripe", "Citadel"
  • Role (optional but improves results) — e.g. "software engineer", "data scientist", "backend engineer"

If the user hasn't provided a role, default to "software engineer" and mention it in the output.


Step 2 — Parallel scraping

Run all three agents simultaneously. Each lands directly on a results page — no unnecessary navigation.

Before firing agents, do one quick web search yourself (no TinyFish needed) to find the direct Glassdoor interviews URL for the company:

Search: site:glassdoor.com "{COMPANY_NAME}" interview questions

Take the first result URL that looks like: https://www.glassdoor.com/Interview/{Slug}-Interview-Questions-E{ID}.htm

Use that exact URL in Agent 1 below. If you cannot find it, fall back to: https://www.glassdoor.com/Interview/{COMPANY_NAME_ENCODED}-Interview-Questions.htm

# Agent 1 — Glassdoor interview reviews (land directly on interviews page)
tinyfish agent run \
  --url "{GLASSDOOR_INTERVIEWS_URL}?filter.jobTitleExact={ROLE_ENCODED}" \
  "You are on a Glassdoor interview reviews page for {COMPANY_NAME}, filtered to {ROLE}.
   Read the first 5 visible interview cards only. Do NOT scroll. Do NOT click any card.
   From the preview text of each card extract:
   - Role title
   - Interview difficulty (Easy / Medium / Hard / Very Hard)
   - Outcome (Got offer / No offer / Declined)
   - Interview questions verbatim
   - Topics mentioned (dynamic programming, system design, behavioural, etc.)
   - Any tips or regrets
   STRICT RULES:
   - 5 cards maximum — stop immediately after the 5th
   - Do NOT click any card, do NOT paginate, do NOT scroll
   - If the page asks you to sign in, return an empty array immediately
   Return JSON array: [{role, difficulty, outcome, questions: [...], topics: [...], tips: [...]}]" \

# Agent 2 — Blind interview discussions
tinyfish agent run \
  --url "https://www.teamblind.com/search/{COMPANY_NAME_ENCODED}%20interview" \
  "You are on Blind search results for '{COMPANY_NAME} interview'.
   Read the post titles and preview text visible on this page.
   Extract from the visible content:
   - Any specific interview questions mentioned in titles or previews
   - Topics that appear frequently (e.g. system design, LC hard, SQL, coding rounds)
   - Difficulty signals (e.g. 'brutal', 'straightforward', 'multiple rounds')
   - Role types mentioned
   STRICT RULES:
   - Do NOT click any post to open it
   - Do NOT scroll more than twice
   - Do NOT navigate away from this page
   - Read only what is visible in post titles and preview snippets
   Return JSON: {questions: [...], topics: [...], difficulty_signals: [...], roles_mentioned: [...], tips: []}" \
  --sync --browser-profile stealth > /tmp/ip_blind.json &

# Agent 3 — Reddit interview experiences
tinyfish agent run \
  --url "https://www.reddit.com/search/?q={COMPANY_NAME_ENCODED}+{ROLE_ENCODED}+interview+experience&sort=relevance&t=month&type=link" \
  "You are on Reddit search results for '{COMPANY_NAME} {ROLE} interview experience'.
   Read the post titles and snippet text visible in the search results — do not click anything.
   Extract:
   - Interview questions mentioned directly in titles or snippets
   - Topics that appear across multiple posts (system design, behavioural, OOP, etc.)
   - Difficulty language used
   - Rounds mentioned (phone screen, onsite, take-home, etc.)
   STRICT RULES:
   - Click a post ONLY if its title explicitly says 'interview questions' or 'prep guide' — max 2 clicks total
   - On any clicked post: read only the top-level post text, skip all comments, do NOT scroll
   - Do NOT paginate
   - Stop after reading 10 result snippets
   Return JSON: {questions: [...], topics: [...], rounds: [...], difficulty_signals: [...], tips: []}" \
  --sync --browser-profile stealth > /tmp/ip_reddit.json &

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
