Does GhostPilot work with HackerRank and CoderPad?

It runs as a browser side panel alongside them. Coding mode captures the problem on screen with one shortcut and returns a worked solution, and because the panel is not part of the editor tab, sharing that tab does not capture it. Sharing your entire screen does. You still have to explain the query out loud, which is most of the score.

Can GhostPilot help with A/B testing and statistics questions?

It detects the question from the call audio and surfaces a structured answer about two seconds after it ends, which helps on questions like what a p-value of 0.04 actually means and what you would check before shipping. Live transcription also keeps the exact figure on screen, since the answer changes entirely if you misheard the number.

What does GhostPilot give me after a data analyst interview?

A debrief with per-answer scoring and a PDF export, so you can see which case answer was hand-wavy and where you talked past a stakeholder question, plus a follow-up email generator. Analyst loops repeat questions across rounds, so the reusable answer library is worth filling in before the first screen rather than after the third.

For data analysts

Live SQL on a shared editor, then the case that decides the loop.

A data analyst loop is three to five rounds: a recruiter screen where answering "SQL on a scale of one to ten" quietly sets the difficulty of everything after it, a live SQL screen on HackerRank or CoderPad, a case study that decides most loops, a behavioural round, and often a presentation of your take-home. GhostPilot runs in the browser side panel alongside them.

How it fits data analyst interviews

Scenario 01

The live SQL screen on HackerRank or CoderPad

Second-highest salary. Find the duplicate rows, then remove them. A running total of revenue by day. The time sink is rarely the logic, it is reaching for the right window function under a clock: DENSE_RANK() against a MAX subquery, ROW_NUMBER() inside a CTE for the deduplication, the frame clause on a running total. Coding mode captures the on-screen problem with one shortcut and returns a worked solution, in the side panel rather than inside the editor tab. You still explain the query out loud.

Scenario 02

The statistics question hiding inside an easy sentence

"A p-value of 0.04 came back on an A/B test. What does it actually mean, and what would you check before shipping?" A structured answer arrives about two seconds after the question ends: what a p-value does not mean, sample ratio mismatch, statistical against practical significance, and which guardrail metrics you would check before calling it a win. Live transcription keeps the exact figure on screen, which matters, because 0.04 and 0.4 are different answers and call audio does not always agree.

Scenario 03

"Daily active users dropped 8% week over week. How do you investigate?"

The product case, and the failure mode is theorising before segmenting. Rule out instrumentation before you rule out the users, then cut by platform, geography, cohort, plan and new against returning. Behavioural and technical questions are handled differently, so the stakeholder half of the loop ("someone asks you for a dashboard of everything") comes back as a conversation you could actually have, rather than a feature list from Tableau or Looker.

What runs during the call

Auto-opens on Google Meet, Zoom and Microsoft Teams. It hears the call tab's audio and never asks for your microphone.
Live transcription and automatic question detection, with a structured answer about two seconds after a question ends.
Coding mode: one shortcut captures the problem on screen and returns a worked solution, which is the SQL screen in practice.
One-key hide, click-through mode, and a compact plain-notes popout for when the editor already owns your screen.
Afterwards: a debrief with per-answer scoring, PDF export, a follow-up email generator, and a reusable answer library.

The take-home itself is offline work and nothing here touches it. The round where you present it is live, and that is the one people underprepare.

Screen share, honestly

The accurate version, because a wrong answer here costs you the interview. The Chrome extension lives in the browser side panel: it is not captured when you share a single tab, nor when you share a window with the panel popped out. Like every extension, it is visible if you share your entire screen. The Windows desktop app is different. It excludes its own window at the operating-system level, so it stays out of screen shares, recordings and screenshots, and sits in the taskbar as "GP Helper".

SQL screens usually run in a HackerRank or CoderPad tab, and a tab share does not capture the side panel. If your interviews force a full-screen share, the desktop app is the right tool, and the only one we would stand behind.
