Is ChatGPT good for interview prep?

ChatGPT is genuinely useful for the early-stage thinking work: generating practice questions, talking through your stories, drafting responses. It costs nothing and is instantly available. Where it falls short: it doesn't probe missing evidence (it'll happily ask 'can you tell me more?' rather than 'where's the outcome?'), it doesn't research the specific employer, and it scores nothing, so you can't tell whether you actually got better. For genuine practice, you need probing rather than reps.

What can ChatGPT do that Electric Interview can't?

Three things: it's $0, it's available right now in another tab, and it'll roleplay any persona on demand. If you want to brainstorm questions for a niche role, draft a follow-up email, or talk through a story while you walk the dog, ChatGPT is faster and cheaper. Electric Interview is purpose-built for one specific job (running a personalised practice interview against a specific role with a coaching report) and won't do those other things.

Why would I pay $7 when ChatGPT is $0?

Electric Interview spends about 3–5 minutes researching the actual employer (their values, strategic priorities, leadership), reads your CV against the specific job description, and generates a question bank designed around the gaps it finds. The interviewer probes missing evidence rather than asking generic follow-ups. Afterwards you get a coaching report scored across six dimensions with specific imperative actions. ChatGPT can do bits of this if you prompt it carefully each time; Electric Interview is the integrated loop.

What's the best no-cost alternative to Electric Interview?

ChatGPT with a careful prompt is the best no-cost alternative. The honest version: paste your CV and the job description into ChatGPT, ask it to play a senior interviewer for that role, and tell it explicitly to probe missing scope, ownership, outcome, and trade-off rather than asking 'tell me more'. You won't get the employer research or the scored report, but the practice itself is roughly two-thirds as useful as a structured tool, at $0.

Electric Interview vs ChatGPT for interview prep: which is better?

ChatGPT is the right call if you want free, instant brainstorming or a flexible practice partner you can prompt into any role. Electric Interview is the right call if you want a structured, employer-specific practice interview with a scored coaching report. The two are optimised for different jobs. Below: where each one wins, point by point.

Dimension	Electric Interview	ChatGPT
Reads your CV against the specific role	Built around CV + JD pairing.	Only if you paste both each time and prompt carefully.
Researches the actual employer	Pulls leadership, values, and strategic priorities.	Knowledge cutoff; no live research unless you wire up browsing.
Probes missing evidence specifically	"Where's the outcome?", "What was your specific role?", "What was the trade-off?"	Defaults to "can you tell me more?"; needs explicit prompting to probe.
Scored coaching report	Six dimensions per question + imperative next moves.	No persistent rubric; you'd have to ask it to score every time.
Voice / posture / body-language analysis	Deliberately not: research says it's the wrong input.	Not built for it.
Cost	$7 USD per role, one-off. No subscription.	$0 tier; $20/month for ChatGPT Plus.
Privacy	CV deleted after 30 days. Not used to train AI.	$0 tier conversations may be used for training unless you opt out.
Time to value	3–5 minutes to generate the brief; 18–28 minutes for the practice interview.	Instant if you have a prompt ready.

Where ChatGPT actually works for interview prep

ChatGPT is excellent for the brainstorming half of interview prep. Drafting a 60-second tell-me-about-yourself, generating practice questions for an unfamiliar role, talking through a story while you wait for the bus: all of that. It’s free, it’s instant, and it’ll play any persona you ask for. If you’re prepping for a junior or mid-level interview where the bar is “tell me a coherent story”, ChatGPT plus a careful prompt covers most of what you need.

Where it falls short for senior interviews

ChatGPT’s default mode of asking follow-up questions is to say “can you tell me more?”. That’s an inert follow-up: it asks you to keep performing rather than to produce the specific evidence you left out. A senior interviewer doesn’t do that. They probe. “What was yourspecific role?”, “What was the actual outcome (a number, a decision, a behaviour that stuck)?”, “What was the trade-off you made to get there?”. The structured-interview research is direct: probing missing evidence is what moves performance, not unguided practice reps. Without a probing rubric, you can spend an hour on ChatGPT and walk in no sharper than when you started.

Employer research: ChatGPT can’t do this without help

ChatGPT’s knowledge has a cutoff. It can’t tell you what was on the company’s last earnings call, what their CEO said on a podcast last month, or what the recent layoffs are likely to mean for your role. Electric Interview spends about 3–5 minutespulling that information per session and weaves it into the question bank, so when the interviewer pushes you, the questions reflect the actual context the real interviewer will have. ChatGPT can do this if you wire up browsing and explicitly ask, but it’s manual every time.

Scored feedback vs “feels confident”

If you ask ChatGPT for feedback on your answer, it’ll usually give you a mix of encouragement and vague suggestions: “That sounded confident. Try to be more specific about outcomes.” That’s decoration, not feedback. The formative-feedback literature converges on a simple shape: real feedback names the missing observation, explains the stakes, and hands you the imperative the candidate could execute tomorrow. Electric Interview’s coaching report scores every answer across six independent dimensions (relevance, specificity, ownership, trade-off, structure, clarity) with a one-sentence imperative for each weak area. ChatGPT can be prompted to do this once; it’ll forget the rubric the next time.

The cost question

ChatGPT's basic tier is $0. ChatGPT Plus is $20/month. Electric Interview is $7 per role, one-off, no subscription. If you’re going to do nine practice sessions for one role (which the dose-response research suggests is roughly the inflection point), the comparison is $7 vs whatever your time is worth re-prompting ChatGPT each time. If you’re prepping for one role, $7 is cheaper than the coffee you’d buy to think about it. If you’re prepping for ten different roles, ten times $7 is still less than two months of ChatGPT Plus.

What ChatGPT genuinely beats Electric Interview at

Three things. It’s free for the marginal session. It’s instant: open in another tab. And it’ll do anything you ask, including the bits Electric Interview deliberately doesn’t do (negotiation roleplay, non-interview career conversations, day-of-interview pep talks). For early-stage thinking, ChatGPT is the right tool. For the actual practice loop right before a senior interview that matters, Electric Interview is purpose-built for the job.

Bottom line

Use ChatGPT for early brainstorming, drafting answers, talking through ambiguous scenarios, or when you need free instant practice for a role you’re not yet sure about. Use Electric Interview for the actual practice loop in the fortnight before a senior interview: when you need an interviewer that probes the right gaps, employer-specific questions, and a scored coaching report you can actually act on. Many candidates use both. The $7 is well-spent for the role that actually matters.
