ChatGPT vs Claude: which helps you prep interviews
Use ChatGPT if you want to rehearse out loud: its voice conversations let you run a mock interview and answer questions as you would in the room. Use Claude to work through the written side, such as a long job description, your CV and the company's annual report, where its careful reading of long documents pays off. Try each on the same job advert before deciding; you can do that without paying.
Which one to pick
You want spoken practice with follow-up questions, or need it to search the web for recent news about the company before the interview.
You paste in a long job spec, your CV and company documents and want a careful answer plan built from all of them at once.

Questions
Can I prepare for an interview on the free plans?
Yes. ChatGPT and Claude both offer a free plan that covers practice questions, feedback on answers and help with your CV. A paid plan's higher limits matter only if you rehearse for hours every day. For one or two interviews, the free tiers are enough.
Which one is better for a spoken mock interview?
ChatGPT. It holds voice conversations, so it can ask you a question, listen to your answer and come back with a follow-up. That is close to the pressure of a real interview. Claude is stronger once you move to written prep: refining answers and checking them against the job description.
I already use ChatGPT. Is it worth switching to Claude for this?
Only if your prep leans on long documents. Claude handles long texts and careful reasoning well, so it suits a detailed job spec, a case study or a company report. Keep ChatGPT for voice rehearsal and web search. You can also keep both, since the free plans cost nothing.
Do they work for interviews in Spanish, German, French or Italian?
Both are available across the UK and the EU countries we cover, and both reply in the language you write in. You can ask for questions in German and answers checked for tone in French. Ask them to correct your grammar too, which helps when the interview is not in your first language.
Can they research the company for me?
ChatGPT searches the web, so it can pull recent news, product launches and press coverage before your interview. Claude is the better reader of documents you give it, such as an annual report or the full job pack. Check any fact before you repeat it to the interviewer, since both can get details wrong.
